Three teenage girls with psychic abilities join a military expedition to investigate strange anomalies in the Pacific, where they conduct aerial reconnaissance from an aircraft carrier and encounter a living UFO that one of the girls recognizes from her extraordinary past. During their debriefing, it's revealed that one team member is a human-alien hybrid who was raised on a UFO, another is a time traveler from millions of years in the future, and their psychic visions uncovered evidence that nuclear testing in the 1940s accidentally destroyed alien facilities existing in parallel time dimensions.
