| Part 1: Years ago, Hamato Yoshi, a Japanese ninja master, moves to New York City and purchases four baby turtles, before witnessing a shady deal in an alleyway; in the resulting fight, he and the turtles are coated by a strange chemical mutagen, transforming Yoshi into a humanoid rat and the Turtles into anthropomorphic form. In the present, Yoshi, now known as Splinter, has trained the Turtles—Leonardo, Donatello, Michelangelo and Raphael—in the art of ninjutsu, and celebrates their fifteenth "Mutation Day" with them. Splinter begrudgingly allows the Turtles to visit the surface world, where they encounter pizza for the first time and observe a teenager named April O'Neil, with whom Donatello becomes infatuated. April and her father Kirby are then attacked by a group of strange men, and, unable to work together, the Turtles fail to stop them from being kidnapped—immediately after, Michelangelo discovers that the kidnappers are androids piloted by brain-like aliens, but the other Turtles dismiss him. Splinter chastises the Turtles for their failure, yet agrees that they have to take action, deeming Leonardo the Turtles' leader in order to help them function as a team. The Turtles track down the kidnappers' van and their associate, Snake. In the process, they discover another canister of the chemical mutagen. Part 2: The Turtles interrogate Snake using the Mutagen, learning that the kidnappers are called the Kraang and that they have been kidnapping scientists across the city. Snake escapes soon afterwards, and overhears Leonardo and Raphael discussing a fake plan to rescue the O'Neils. The Turtles recoup in the lair, where Splinter warns Leonardo that every leader must prepare to face failure, recounting the story of how he lost his wife Tang Shen and daughter Miwa in the final battle with his rival, Oroku Saki. The Turtles sneak into the Kraang's base, where Michelangelo accidentally triggers the alarms, and the Kraang try to make off with the O'Neils. Before the Turtles can rescue them, they end up in a fight with Snake, who had been exposed to the Mutagen and transformed into a giant weed monster, which Michelangelo dubs "Snakeweed". Donatello rescues April but is forced to leave Kirby, while the other Turtles electrocute Snakeweed. Once they have escaped, April is left with her aunt, and Splinter expressed pride in Leonardo's leadership. The news reports a supposed ninja sighting; and, watching the report in Japan, Oroku Saki, now known as the Shredder, realizes that Hamato Yoshi is still alive and decides to travel to New York to finish their battle. |||||||||

The Turtles attempt to reason with Vic to get the video, but Raphael's anger once again gets the better of him, resulting in the Kraang kidnapping Vic. Leonardo orders Raphael to return to the lair, where Splinter tells him the story of how he allowed his own temper to grow out of control in an argument with Oroku Saki, which transformed their rivalry into bitter hatred, using this to teach his son to let go of his anger.
