Professor Kenneth Parker, a God-fearing physical culturist, arrives to work in the serene little town of River's End.

The Browning's daughter, Kitty, has taken an interest in the professor's assistant, Bill Ferris, and started an extreme diet to seem more pleasing to him.

Kitty's condition gets worse and Dr. Christian, exhausted from an abnormal workload because of the professor's teachings, manages to visit her.

Dr. Christian finally discloses the professor and his cultist teachings as a public hazard.

The heresies of the professor come to Bill's knowledge, and he finally realizes that his boss is a fraud.
