Korra and the Fire Ferrets prepare for the pro-bending finals, as Amon threatens the United Republic Council to cancel the tournament lest severe consequences follow. At the Avatar and Lin Beifong's bidding, the Council disregards the threat and allows the Pro-bending Tournament to proceed. Right after the conclusion of the match, Amon and his Equalists attack the arena. After Amon openly declares war on the benders, the Equalists retreat and partially destroy the building, frustrating Lin and Korra's halt attempts.
Korra, Mako, and Bolin are training for the pro-bending championship match by destroying pictures of Tahno when they hear Amon's voice on the radio. He commands the United Republic Council to shut down the Pro-bending Arena and cancel the finals, threatening "severe consequences" if they fail to comply.
Not waiting to find out the Council's decision via the media, the Fire Ferrets head down to City Hall on Naga. When they barge in, Korra calls upon her status as the Avatar and a pro-bending player to be heard. However, Tenzin and Tarrlok explain that the Council had already unanimously voted to close the arena. Korra does not understand, as she surely thought that Tarrlok would want to take a stand against Amon. He informs her that while he is still committed to bringing Amon to justice, he is unwilling to risk innocent lives just to let them "play a game", but the team does not give up and tries to persuade the councilors to change their minds, arguing that pro-bending might be only a game to him, but it brings all the people of the city, benders and nonbenders alike, together in peace and thus serves as an inspiration to everyone. However, to no avail, as the Council is not affected by their "naive idealism". As a last effort, Korra states that closing the arena down is the equivalent of letting Amon win, but Tarrlok ignores her statement and readies his gavel to proclaim the meeting adjourned. However, much to the surprise of everyone, Lin Beifong intervenes by destroying the gavel with her metal cable and sides with the Avatar. The chief argues that it is time the benders of the city opposed the Equalists and she offers to provide extra security with her officers during the match and to take full responsibility for the spectators' safety if the Council would keep the arena open. Tarrlok sarcastically states that it is hard to argue with Lin's excellent track record and that she has his support if the chief is confident she and her officers can protect the arena. Much to the Fire Ferrets' pleasure, every Council member, except Tenzin, changes their vote and the tournament is allowed to continue.
Once the decision has been finalized, Tenzin invites Lin to have a talk with him away from the others. In the hallway, he expresses his concern for her safety, stating that Tarrlok is simply playing her. When Lin bluntly states that she knows what she is doing, Tenzin announces that he will accompany her during the match. Albeit annoyed, she allows him to do so. When Korra comes up to the duo and passes Lin, she thanks her for her help; however, the metalbender completely ignores Korra. This urges her to ask Tenzin what Aang did to make Lin hate the Avatar, believing that was where the source of Lin's annoyance lay. Tenzin explains that her attitude had very little to do with Aang and the Avatar, but more with himself. Remembering what Pema told her the other day, Korra realizes that Lin and Tenzin used to be romantically involved. Taken aback by the statement, Tenzin begins to explain their story, but stops halfway through, saying that it was none of Korra's business and that they had moved passed it since it had happened.
Meanwhile, in a warehouse somewhere else in the city, Amon supervises the loading of four trucks with wooden crates. The Lieutenant approaches him and enlightens him about the Council's decision to ignore his warning and keeping the arena open. Amon is pleased with this news, stating that "everything is going according to plan".
That night, the Metalbending Police Force has deployed a multitude of boats, airships, and trucks to secure the arena. Before the match begins, several officers execute a security sweep of the building, including the stands. As Lin is finishing the check, Tenzin inquires how things are going. Annoyed, she brashly answers his questions and asks him to leave her to do her job. However, Tenzin does not back away and states that it would be nice if they could help each other out "like old times", even if it was only for one night. Lin complies, stating that she would try to be "less abrasive than usual".
As the match begins, the arena fills with spectators. Right before the start of the match, Bolin gives Pabu a pep talk, stating that the fire ferret would do great. The trio is subsequently called to the stage by the ring announcer. As the team approaches the playing field under the loud applause of the spectators, Asami, from an exclusive platform, blows a kiss to Mako and winks to him, which the firebender returns, much to Korra's annoyance. The moment they arrive on the field, Bolin and Pabu begin performing a trick as a way of introducing the team, which involves Pabu walking on his front legs and jumping through the middle of an earth disk; the trick only receives a mediocre response from the crowd. The reigning champions, the White Falls Wolfbats, are introduced shortly. The team has donned themselves in capes and wear wolfbat masks. Their introduction is accompanied by an excessive display of fireworks around the stadium, performance that an astonished audience applauds. Dismayed, Bolin dismisses their entrance, saying "anybody can howl", and commenting that they have nothing on him and the fire ferret. Korra is gravely annoyed by Tahno's extravagant entrance and proclaims that she is going to knock Tahno's "stupid hair off his stupid head".
As the match begins, it immediately becomes apparent that the Wolfbats are not interested in playing by the rules. Tahno displays an obvious "hosing foul" against Bolin, but it is not called by the refs. With a variety of tricks and fouls which remain unpunished by the referees, the Wolfbats manage to push the Fire Ferrets back to zone three and eventually off the playing field. However, Korra manages to hold up herself and Mako on the edge of the ring with one hand. With an incredible effort, she tosses him back onto the playing field while letting herself plummet down into the water. Before landing, Mako knocks the celebrating Tahno down with a fire blast in the back, just as the buzzer sounds to end round one.
Before the start of round two, the Fire Ferrets briefly communicate on their best strategy against the unfair tactics of the Wolfbats. Korra suggests that if their opposing team is going to play dirty, they should do the same; however, Mako refuses to do so, as the only explanation for the Wolfbats ability to play as they were doing was that the referees had been paid off, and thus the Fire Ferrets would not be able to disobey the rules. Reluctantly, Korra agrees. After a fierce round two with some illegal ice moves and fire shot to the head by the Wolfbats, the round ends in a tie. The Fire Ferrets win the coin toss and Korra immediately decides that it would be a water against water battle. Tahno taunts Korra, inviting her to give him her best shot. He evades her first blast, but the Avatar delivers another one, striking Tahno in the chin. The impact is so strong that Tahno's helmet is sent flying into the audience and caught by some Fire Ferrets fans, and he is knocked off the platform. In return, Korra taunts him by calling him a "chump".
From the stands, Lin and Tenzin are viewing the match. Upon witnessing Korra's easy victory, Lin expresses disbelief at the fact that the soft-hearted Aang was reincarnated in tough Korra. Tenzin remarks that Korra reminds him of a young Lin and that they would likely get along if the chief would give her a chance.
After taking the round, the Fire Ferrets regain some hope to win the finals. The teams are more or less matched, but Ming tips the scales in the favor of the Wolfbats when he scatters an earth disk and Tahno sends three water blasts containing pieces of rocks at the Fire Ferrets, knocking them off the ring and into the water. Although Shiro Shinobi proclaims that there would be no way that the knock out would be called legitimate, the referee pronounces the Wolfbats as the winners and the champions for the fourth time. As the Wolfbats celebrate, numerous spectators in the audience cover up their faces with a cloth that bares the Equalists insignia, the typical red circle. They each retract an electrified glove out of their popcorn cartons and use it to take out Lin, Tenzin, and all the policemen in the arena.
Korra and her teammates emerge from the water, and their attention is immediately drown toward electricity waves that are visible in the audience. The Lieutenant appears at the side of the pool and, just before Korra can hit him with a waterspout, he knockes out the Fire Ferrets by sticking his charged weapons in the water. Meanwhile, Shiro Shinobi comments on the strange events happening in the stands just before he is too stunned by an Equalist.
As his henchmen take out the security all around the stadium, Amon and some other Equalists appear in the middle of the ring. The Wolfbats attack them, but after a short duel, they are overpowered and Amon takes away their bending. The Equalists kick the defeated Wolfbats into the water and simultaneously, Equalist banners appear all around the arena.
Meanwhile, Korra, Mako, and Bolin are being dragged out of the pool to be tied up to one of the playing field's support beams. While teetering on the brink of unconsciousness, Korra has another vision of an adult Toph and Aang as they face Yakone.
Amon makes a speech to the entire audience, commenting that it seems fitting that they would all celebrate the victory of "three bullies who cheated their way to victory" as they do the same every day to the nonbenders of the city. He states that the fate of the Wolfbats should serve as a warning to all the other benders of the world; everyone who stands in his way would suffer the same fate. Amon called out to his followers as well, stating that they now had the numbers, the strength, and the technology to overthrow the bending regime and replace it with a fair minded Equalist government. He ends his speech by openly declaring that the revolution has begun.
After waking up during Amon's speech, the team sees Pabu swimming toward them, so Bolin immediately instructs him to chew through the ropes binding them. However, while the ferret is still gnawing at the ropes, Amon and his followers are already ascending to the roof, preparing to escape via airship and blow up the pro-bending ring as they go. The moment Pabu succeeds in freeing the Fire Ferrets, Korra sets out in pursuit of the Equalists, riding a waterspout to the top of the arena. The water does not hold enough power, and Korra plummets down. As she is falling, she is suddenly caught by a metal cable thrown by Lin, who is swinging from the top of the arena and uses her own momentum to launch Korra toward the escaping Equalists.
Korra succeeds in knocking some Equalist fighter off of the little platform they were standing on while being hoisted into the airship. She briefly glances around and sees that the wreckage of several burning police vehicles are scattered all across the bay. Although the Avatar fiercely attacks Amon and the other Equalists with her firebending, the Equalist leader remains outside her grasp and she is knocked off the platform soon after.
A battle ensues on the glass dome of the arena between Korra, Lin, and several Equalists. As Lin attempts to pull herself up toward the airship with her metal cables, she is knocked over by an electrified attack from the Lieutenant. However, before he can finish her off, Korra comes to her rescue and forces the Lieutenant on the run with her firebending. A one-on-one battle commences between the two while Lin immobilizes the other fighters and hoists herself up toward the airship. Korra manages to overpower the Lieutenant and knock him off the arena; however, the strain of the fight proves to be too much for the glass dome and it caves away underneath her. Lin sees that Korra is falling through a certain death and ceases her pursuit of the Equalists. She uses her metal cables to propel her down after Korra and manages to catch the Avatar in midair, the two landing safely in the stadium's bleachers.
Korra thanks Lin for saving her life. As they both watch the Equalist airship fly away from the arena, Korra is welcomed back by Mako and Bolin, who each hug her in relief. As Tenzin walks over to them, Lin expresses her annoyance and disappointment of having played right into Amon's hand. Tenzin comforts her by stating that he had not only played her, but everyone. He concludes by stating that Republic City is now at war.
