Sister Sparrow has been abducted from the Master of Light Institute by the evil Saint Offender (Joe Estevez). Before Hawk can complete his task, he must take psychedelic mushrooms with cult movie actress Karen Black and learn to rollerblade. Armed only with his samurai sword, Hawk does battle with the Black Knight (Frank Stallone), rollerblading ninjas and other gangs that inhabit the Wheelzone. Joining him on this mission are a Kabuki mime with a wiffle bat, a rollerblading banjo player entirely swathed in bandages and a pacifist named Stella Speed.
