For fifteen years, four mutant Turtles and their rodent sensei have lived a secret life beneath the sewers of New York. Coming to the surface for the first time, the Turtles soon find their day out interrupted as a young girl and her father become the targets of mysterious, and dangerous, men...

The Turtles are in danger of exposure when hot-headed Raphael is caught on video arguing with a human on the street. He must learn to control his temper in order to help the others retrieve the video before it falls into the wrong hands.
