Roller Blade (1985)

This low-budget martial arts fantasy adventure is set in LA after WW III and chronicles the battle between the wheelchair-bound peacenik nun Mother Speed and the wicked Dr. Saticoy. It seems that Mother possesses a special crystal (used in their worship of a big yellow "have a nice day," smiley face). The bad doctor and his skate-boarding goons are desperate to get it. Unfortunately, she is protected by her roller-blading beauties and he must send in a decoy in order to get it. Yes, it is as campy as it sounds. ~ Sandra Brennan, Rovi
