Linda Danvers and two of her college friends are sent on a trip to the South Pacific to collect specimens for their school aquarium. Their boat navigates a storm and lands on an uncharted island populated by Amazons. The Amazons put them to work as slave girls. The girls also drink a special nectar which will give them Amazon strenght.

After a difficult day working as slaves for Queen Jarta, the girls are tired. Linda decides to pretend that the nectar has taken effect. She begins using her powers to perform tasks ordered by the queen. However, Linda cause damage while doing them. Finally, the queen is so angered she banishes the girls from the island, so they can return home.
