Turtles all restrained. Looks like that bit from the rumored script stayed
As the film opens, an army colonel named Schrader stashes some secret government material by the name of Project Aries underneath a furniture factory where Casey Jones, a hockey-playing 18-year-old, works. Casey gets suspicious and finds, to no surprise, four captive bulky, six-foot turtles proficient in martial arts. He takes pity and frees them, and they make a daring escape. The Turtles then introduce themselves to Casey and explain their backstory, the one TMNT fans know and love.
