Nightclub female second-rate singer Deloris (Hooper Goldberg) was chased by a gang leader after accidentally witnessing a murder. In order to escape the killer's pursuit, she turned to the police. To protect her as a witness at the scene, the police arranged for her to hide in the world. The safest place-a nunnery. The quiet and deserted life of the nunnery made Deloris, who had always been active, unbearable, so she ran out to sing and dance at night while no one was aware. The dean (Maggie Smith) was worried that something would happen to her and arranged her in the choir. She thought the choir was extremely bad and decided to transform it. So during Mass, the choir sang popular songs, but the lyrics were changed to praise God. Unexpectedly, this move was warmly welcomed by the faithful and attracted the Pope's special visit to appreciate it. How can the TV station let go of such interesting news? However, when it was exposed on TV, Deloris was also announced that she would escape again.
