Easter Island has long been the subject of curiosity and speculation. A triangle of volcanic rock in the South Pacific, Easter Island is over 2000 miles away from the nearest population center, making it one of the most isolated spots on Earth. It is best known for the giant stone statues, known as the Moai, that dot the coastline.

A crew of Martians overhears a radio broadcast of Orson Welles' "War of the Worlds" coming from Earth, and, thinking the Martian fleet is attacking Earth, they land their broken-down ship in a backwater mid-American town. As luck would have it, they land on Halloween and get mistaken for trick-or-treaters. Comedy ensues as the Martians try to get taken seriously.
