The Shakiest Gun in the West

In 1870, bumbling Philadelphia-based dentist Jesse W. Haywood (Don Knotts) travels west to set up a practice in the frontier. There, he meets Penelope Cushings (Barbara Rhoades), a pretty bandit who has agreed to investigate an Indian gun-smuggling operation in exchange for her freedom. When their wagon train is attacked, Penelope shoots several Indians dead. However, Jesse falsely assumes it was his errant gunshots that saved the wagon, and soon earns a reputation as a great gunslinger.
