O'Neil burned the lab down, at the cost of his own life.
He tells her that her father was working with Sacks and Shredder, but he learned that Shredder was planning something evil, and so Dr. There, she meets Splinter, who remembered April before he mutated. She goes alone and the Turtles take her into their lair. April logs onto her computer to find some news on the Turtles in the subway, only to find that Donnie hacked her computer and sent her an address for her to meet them at. She shows Sacks the photo of the Turtles, and he takes her into his room to tell her about his past in Japan, being abandoned by his father and learning of a legend about a ruthless warlord in the area. Afterwards, Vern takes her to the Sacks Estate so she can personally ask Sacks about what he and Dr. April continues digging into the Turtles' past, and she tells Thompson about what she saw the previous night. Mikey admits they were out fighting the Foot Clan and when he mentions April's name, Splinter is alarmed and he orders the Turtles to go find her. Splinter breaks Mikey by tempting him with (what else) pizza. However, he manages to catch them and punishes them by making them maintain balance on certain items until they tell him why they were out on the streets. She even recognizes the symbol from earlier as meaning "family." The Turtles try to sneak back into their lair without alerting Splinter. She personally named them and fed them pizza, which they all loved. April sees a video of her as a kid recording in her father's lab, using a mutagen on the Turtles and Splinter, pre-mutation. April runs home and opens a box filled with documents, pictures, and videos on Project Renaissance, what her father and Sacks were working on. The Turtles leave, but April still manages to get a picture of them from a distance. Mikey reiterates this, and it's obvious he's attracted to April. Donnie wiped April's phone, and Leo hands it back to her, warning her not to tell anybody about them, or they'll find her. When she comes to, she meets the four heroes in a half-shell - the leader Leonardo (Pete Plozek), the brainy Donatello (Jeremy Howard), rebellious Raphael (Alan Ritchson), and goofball Michelangelo (Noel Fisher). She gets grabbed and is confronted by the Turtles, causing her to faint. She snaps a picture, which startles them. April runs out and climbs a fire escape to find the Turtles on the roof. The Ninja Turtles catch them on their cameras, and them ride the subway to find the Foot Clan and beat them down easily, freeing the hostages in the process. Karai calls out the vigilantes to show themselves, or the Foot Soldiers will execute the hostages. April leaves the van to check it out, only to get grabbed by a Foot Soldier and thrown in with other hostages. After the event, April and Vern drive home when they see terrorized New Yorkers scrambling all around the streets. April finds Sacks at an event, where we learn that her father worked with Sacks on a project before he passed away. The NYPD teams up with Eric Sacks (William Fichtner) of Sacks Group Inc to take down the Foot Clan. Karai reports to him about the vigilante activity, and that these non-human creatures must be stopped. We see a man with his hands tied behind his back, and a Foot Soldier trying to attack him, but the man easily takes the Soldier down. She tells her roommate Taylor (Abby Elliott) about this, and also at work to her boss Bernadette Thompson (Whoopi Goldberg), but nobody seems to believe her or care about what she has to say. The figure leaves behind a symbol that April recognizes. April tries to get footage on her phone, when a shadowy figure shows up and takes out the Foot Soldiers one by one. She rides her bike there at night to find the Foot Clan, led by their lieutenant Karai (Minae Noji), preparing to bring something in. April learns from the dock worker that something is being brought in by the docks. April wants to do better stories, but Vern assures her that some people enjoy these kinds of stores the same way they enjoy foam on coffee. Not getting any answers, she and her cameraman Vernon Fenwick (Will Arnett) go into the city to do a puff piece on trampoline fitness. Meanwhile, Reporter April O'Neil (Megan Fox) pesters a dock worker for information on chemical materials that the Foot Clan may be involved with. Beneath the sewers, the rat sensei Master Splinter (Danny Woodburn) has been training his four sons until they are ready to take Shredder on and become heroes.
