Self-diagnosed mental patient John Burns has to report to Dr. Lawrence Baird's office after causing a riot in the hospital cafeteria.

Burns arrives in Los Angeles, where he is met by Dr. Maitlin's radio show assistant, Dr. Laura Rollins, and escorted to the waiting limousine.

He crosses paths with Donald Becker, a crazy faux priest who is collecting money to save plants.

Appearing on the radio talk show, Burns is a huge hit, offering people free consultations and using profanity on the air.

Burns has been paid for the show (in cash) and is ready to leave town when he sees on the in-flight TV that Becker is on top of the Hollywood sign, shouting Baird's name.
