A cidade precisa de heróis. A escuridão instalou-se em Nova Iorque desde que Shredder colocou o seu punho de ferro em todo o lado.

O futuro é cruel até quatro improváveis irmãos se erguerem dos esgotos e descobrirem o seu destino como Tartarugas Ninja.

Estes heróis mutantes vão ter de trabalhar com a destemida repórter April O’Neil para salvar a cidade e travar os planos diabólicos de Shredder.

Enquanto invadem o ambiente hostil da Central da TCRI, as tartarugas descobrem a verdadeira intenção dos Kraang e decidem impedir a invasão dos aliens de uma vez por todas.

The Turtles — Leo, Raph, Donnie and Mikey — each will go it alone for the first time. Faced with new threats and teaming up with old allies, the Turtles will discover who they really are when they don’t have their brothers at their sides.

When four pet turtles were bathed in alien ooze, they began to mutate and became the Teenage Mutant Ninja Turtles. Raised in New York City sewers by their foster father and wise sensei, Master Splinter, Leonardo, Michelangelo, Donatello, and Raphael wage war against crime. Led by Master Splinter, the four turtles learn the ancient martial art of Ninjitsu, mastering skills of stealth, weapons, and fighting. They stop evildoers in all forms, whether barbaric gangs, lowlife crooks, deranged cyborgs, or even the crime syndicate The Foot, led by their archrival, The Shredder.
