An unknown spacecraft from outside the solar system is heading towards Earth. Prof. Sharp sends the Bionic Six to make contact the ship before it lands. Both the Bionic Six and the United Air Patrol fail, and the spacecraft lands in front of the U.N. building, revealing its inhabitant: a sentient, English-speaking monkey. The monkey was sent by the Intergalactic Congress to review Earth for entry. However, Scarab has other plans.
