About 10,000 years ago, peaceful aliens from the planet Antarea set up an outpost on the planet Earth, on an island later known to mankind as Atlantis. When Atlantis sank, twenty aliens were left behind, kept alive in large rock-like cocoons at the bottom of the Atlantic Ocean. Now a group of Antareans have returned to Earth to collect them. Disguising themselves as humans, they rent a house with a swimming pool, and charge the water with "life force" to give the cocooned Antareans energy to survive the trip home. They charter a boat from a local captain named Jack (Steve Guttenberg) who helps them retrieve the cocoons. Jack likes Kitty (Tahnee Welch), a beautiful woman from the team who chartered his boat. When he spies on her while she undresses in her cabin, Jack is shocked when he discovers she is an alien. After the aliens reveal themselves to him and explain what's going on, he decides to help them.
