Sister Act (film) When a second-rate lounge singer in a Reno casino, Deloris Van Cartier, accidentally witnesses a murder at the hands of her mobster boyfriend, Vince LaRocca, she finds herself on the run. A smart cop out to nab LaRocca places Deloris in the witness protection program, hiding her out in a convent of nuns. The Mother Superior insists that Deloris—now Sister Mary Clarence—take a job in the convent and she becomes the new choir director. In no time at all she has the group singing hymns with a 1960s beat, spurring unheard of attendance at Sunday Masses. When Deloris is kidnapped and taken back to Reno, the nuns effect a rescue in the heart of the gambling city. With LaRocca captured, Deloris is free to go on her way, but she stays with the nuns long enough to appear in a special performance for the pope. Released on May 29, 1992. Directed by Emile Ardolino.
