Absent-minded professor Oscar Collins, studying in his charmless apartment, is bothered by loud music from the flat next door. Peeking through a tiny crack in the wall, he discovers a gorgeous young model, Penny Lane, and becomes obsessed with her and her swinging hippie lifestyle. In surreal fantasy sequences, he imagines doing battle with Penny's gauche photographer boyfriend for her hand. George Harrison provides the period soundtrack.
