SISTER ACT: On the run after witnessing her Las Vegas mobster boyfriend kill someone, a tacky lounge singer (Whoopi Goldberg) enters the Witness Protection Program--as a nun. Now the convent needs protection--from the new Sister Mary Clarence and her Vegas-style ideas on how to run the choir. A charming comedy and one of Goldberg's best movies. SISTER ACT 2: BACK IN THE HABIT is the sequel to the surprise smash hit SISTER ACT. Whoopi Goldberg returns as Deloris Van Cartier, who, at the film's opening, has become a successful Vegas headliner, belting out undeniably cheesy medleys of R&B hits. The nuns she shielded her identity from in the first film arrive to beg her to help them revitalize their San Francisco Catholic school. Deloris is persuaded to put her Sister Mary Clarence costume back on and work with a bunch of undisciplined street kids as the school's music teacher.
