Story of Foxine LaRue, a tomboyish sort who is being prodded into a show-biz career by her stage mother Gert. Young Mr. Partridge becomes Foxine's agent, principally because he's sweet on the girl's older sister Mary. Blackballed from Hollywood because of her mother's pushiness, Foxine tries to help out Partridge and her own family by cooking up a bizarre publicity stunt, enlisting the aid of easy-going Mexican "papacita" Pascual.
