Mitch and Judy are out-of-work beatniks in need of money. At a party held by one of Mitch's friends, Judy meets an older man named Kenneth. Kenneth is not a beatnik, but he likes to attend their parties. He asks Judy on a date. Mitch encourages Judy to date Kenneth because he seems to have money. Kenneth gives Judy a diamond bracelet which Mitch takes and tries to have it appraised by a jeweler. The jeweler has Mitch arrested, as the bracelet Kenneth gave to Judy was stolen. With Mitch in prison, Kenneth winds up with the ultimate kick when he stabs Judy to death in her apartment. Turns out, he's a serial killer and has a different idea of fun.
