Wealthy, eccentric Luce Cannon thinks he's not wealthy enough and invests in the disturbing Polliwog letter which purportedly proves the Mormon Church wrong. Meanwhile, young university student Sarah Larson reads the Polliwog letter and loses her belief in the Church. Sarah and her entourage fall into a series of misadventures involving polygamists, pyramid-schemers, right-wing militias, and professional forgers; not to mention some talented practical jokers. Peace and sanity are restored when Sarah escapes to Rome to find the young man who believes his peace of mind depends on forgetting her.
