When club singer Deloris Van Cartier witnesses her gangster boyfriend Curtis Shank and his goons commit a murder, she is placed in witness protection in the most unlikely of places; a convent!
Shank vows to find her no matter what, and places a price on her head.
Going undercover as Sister Mary Clarence, she must lay low and stay out of trouble, which in Deloris’ case, is a lot harder than it sounds! Her previous life was full of excitement, parties and thrills and Deloris soon grows tired with the slow, simple life of the nuns. Perhaps leading the church choir may bring back that spark she so misses? Several key changes later and Sunday service will never be the same again as she transforms those tone-deaf sisters into divine divas!
The church may be low on funds, but these new found singing sensations bring donations flowing into the convent. Can Deloris guide the girls to stardom while keeping her identity under wraps?
