Leo, Raph, Donnie and Mikey are four mutated turtle brothers who live in the sewers beneath New York with their father, a Japanese warrior who was mutated into a rat following a violent battle with an enemy from his past. The turtles find their true calling when they find out about strange, glowing ooze being shipped in secret across the city, which leads them to investigate TCRI, a shady tech company in partnership with creepy criminal underworld kingpin, The Rat King.
