In this western comedy, a bogus evangelist and his assistant travel to the town of Friendly and endeavor to rob the West's purportedly most unrobbable bank. Unfortunately, they are not the only bandits planning to rob the bank. Their rivals in robbery include a Mexican bandido and his dullard son. A gunman and his assistant also want to attempt a heist. To make things even more confusing, a Texas Ranger and his six Chinese-American G-men pose as laundrymen to investigate a crooked mayor. They all converge on Friendly at the same time and chaos ensues when they meet.
