An ingenious thief steals Michelangelo's Pieta, worth $30 billion in this farce. The trouble is, he has no buyers and so lets an American gangster have it for $40 and a spaghetti dinner. Meanwhile, the Vatican, not wanting the abduction to become public, sends out a priest to find the thieves and retrieve the statue. The priest, a former Indy 500 winner, proves himself to be more than well-equipped for job.
