Story of an ex-con law student and a girl wanting to become a model. When the two get a job as live dummies in a department store window display they start bickering with each other until they witness a murder through the window. The psychopath murderer looks at them through the window, but they manage to keep still enough. He comes back again to check the two out, not wholly convinced they are just dummies. But then one of them flinches, and the two models become fugitives to the murderer.
