A color-blind psychiatrist is stalked by an unknown killer after taking over his murdered friend's therapy group and becomes embroiled in an intense affair with a mysterious woman who may be connected to the crime.

In this classic hospital farce, Peter Sellers plays Dr. Albert T. Hopfnagel, a greedy, crooked hospital administrator who has perfected the art of bill padding, unnecessary surgery and kickbacks. Mistrusted by patients, and resented by other staffers, his assistant Alice can no longer endure his scams and plots to have him sent to prison - but not for long enough. Sellers again steals the show with an absurd and hilarious character study.

Four children want to invite their friends to a picnic, but they don't know how to use the telephone. Suddenly, the room goes dark and the phone becomes large enough for them to climb into. They walk through a tunnel and meet a man named Telly, who takes them into the world of Telezonia, where they are shown various kinds of telephones. They meet several costumed characters, such as Question Mark, who teaches them how to answer the phone; Q and Z, who show them how to use the phone book; and Exclamation Point, who teaches them how to place a call. By the time they leave Telezonia, they are full-fledged telephone users.
