Now teenagers, the turtles Leonardo (Xolo Maridueña), Donatello (Gianni Decenzo), Raphael (Will Poulter), and Michelangelo (Anthony Turpel), are trained in the art of ninjutsu by their sensei and adoptive father, Master Splinter (Ken Watanabe) and they learn to rely on one another as they unravel the mystery of their existence and train to become the heroes they are destined to be. And they're doing all that while trying to defeat the Shredder (Josh Brolin), an old enemy of Splinter who is training a peculiar band of ninjas while hiding in New York City. When they are in the surface world, the Turtles become involved in a conspiracy involving alien creatures, robotic droids and missing scientists, and they must rise up out the sewers and defend their city against evil forces from both past and present.
