In this follow-up to "The Trouble with Angels", the wry but wise Mother Superior of St. Francis Academy For Girls accompanies a group of nuns including modern, progressive Sister George, with their high-spirited students on a bus trip across America to a California peace rally. Along the way, they encounter a series of adventures that include multiple bus problems, an overnight stay at a Catholic school for boys run by Father Chase, a Western dude ranch owned by millionaire Mr. Farriday, a flamboyant movie director shooting a Western on location, and a bunch of menacing biker toughs.
