Old Burns, who pretended to be a psychopath, was seen through by Baird, a doctor in a mental hospital, and was ready to send him to a prison for felons. At this time, George Maitlin, a famous psychiatrist and radio host in Beverly Hills, took a long vacation because of long hard work, and called Dr. Baird to carry out the business in his place. Unexpectedly, this call was intercepted by Burns, who used a trick to leave the mental hospital, went to Beverly Hills to change into a famous doctor, and took advantage of the opportunity to open his mouth to earn medical treatment and host remuneration, so as to save enough money to flee to Mexico as soon as possible. The sick comedy directed by Michael Ritchie satirizes both the psychiatrist's profession and the values of wealthy people, but it is not done in depth, mainly relying on Dan Aykroyd's wonderful performance to be funny. Veteran comedian Walter Matthew plays a friend who sees through Burns's tricks.
