Sequel to the big-budget reboot of the comic book series following the anthropomorphic ninjutsu-trained turtles Leonardo (Pete Ploszek), Michelangelo (Noel Fisher), Donatello (Jeremy Howard) and Raphael (Alan Ritchson). The turtle's arch nemesis Shredder (Brian Tee) has returned and employed Techno Cosmic Research Institute scientist Dr. Stockman (Tyler Perry) to create some mutants of his own in the form of ferocious duo Bebop (Gary Anthony Williams) and Rocksteady (Stephen Farrelly). Meanwhile, the evil Kraang (voice of Fred Armisen) has arrived from Dimension X to lead an invasion of New York City. With the help of journalist April O'Neil (Megan Fox) and vigilante Casey Jones (Stephen Amell), the turtles face a fight on two fronts to save the city from certain destruction.
