The film follows the adventures of the four Turtles; Leonardo, Donatello, Michelangelo and Raphael. Roughly resuming from the events of the last film, villain Shredder returns to take back command of the Foot Clan, and work towards getting revenge on the Turtles. When he learns the secret behind the Turtles' mutation, he becomes more dangerous than ever. The film sheds some light on the origins of Splinter and the Turtles, introduces two new villains; Tokka and Rahzar. Unlike the first film, this one rarely showed the use of their weapons. Most of the combats were done with their fists.

The film was released in March of 1991, and received mixed reviews from critics and fans. It departed from a lot of the darker feelings of the 1990 film, and in contrast was more light hearted than its predecessor.
