When small-town hockey enforcer Casey Jones witnesses a covert military operation at his dead-end night watchman job, he unwittingly frees four hulking, captive creatures who turn out to be mutant ninja turtles—Leonardo, Raphael, Donatello, and Michelangelo. Forced on the run with the Turtles and his ex-girlfriend, aspiring reporter April O'Neil, Casey discovers their true origin: they were born in Dimension X, prophesied to defeat the tyrannical alien warlord Krang. As Krang merges Dimension X with Earth to power his Technodrome, Casey must abandon his small-town life, embrace his destiny, and help the Turtle brothers fulfill their prophecy—before two worlds collide and New York falls.
