A trio of beautiful girls set out to revolutionize life at a grungy American university - the dynamic leader Violet Wister, principled Rose and sexy Heather. They welcome transfer student Lily into their group, which seeks to help severely depressed students with a program of good hygiene and musical dance numbers. The girls become romantically entangled with a series of men - including smooth Charlie, dreamboat Xavier, the mad frat pack of Frank and Thor - who threaten the girls' friendship and sanity.
