Overview
New York, 1980: airplanes have replaced cars, numbers have replaced names, pills have replaced food, government-arranged marriages have replaced love, and test tube babies have replaced ... well, you get the idea. Scientists revive a man struck by lightning in 1930; he is rechristened "Single O". He is befriended by J-21, who can't marry the girl of his dreams because he isn't "distinguished" enough -- until he is chosen for a 4-month expedition to Mars by a renegade scientist. The Mars J-21, his friend, and stowaway Single O visit is full of scantily clad women doing Busby Berkeley-style dance numbers and worshiping a fat middle-aged man.
