"Sister Act tells the hilarious story of Deloris Van Cartier, a disco diva whose life takes a surprising turn when she witnesses a murder. Under protective custody she is hidden in the one place she won't be found - a Convent! Disguised as a nun and under the suspicious watch of Mother Superior, Deloris helps her fellow sisters find their voices as she unexpectedly rediscovers her own. A sparkling tribute to the universal power of friendship, sisterhood and music."
