The Monkees spend the night in a haunted house to collect an inheritance.

In a computerized toy factory, the Monkees foil an efficiency expert (Stan Freberg) who wants to replace an old toymaker (Walter Janovitz) with automation.

To save a bankrupt circus, the Monkees pose as a troupe of dazzling, supreme high-wire artists from France known as the Mozzarelli Brothers, but get in trouble when their guise requires them to actually perform.

The Monkees attempt to rescue Davy from his girlfriend Lorelei (Arlene Martel), Count Batula (Ron Masak), a wolf man (David Pearl), mummy man, and a Frankenstein-looking monster in a creepy castle.
