NO BOOZE! NO SEX! NO DRUGS!… NO WAY! A Reno singer witnesses a mob murder and the cops stash her in a nunnery to protect her from the mob's hitmen. The mother superior does not trust her, and takes steps to limit her influence on the other nuns. Eventually, the singer rescues the failing choir and begins helping with community projects, which gets her an interview on TV—and identification by the mob.
