Young men and women are vanishing into thin air, leaving clothing behind, layered just as though their bodies evaporated. Julie, a virginal farm girl, is one of the abductees. She suddenly finds herself naked and surrounded by dozens of other naked young adults. She has been snatched and transported into year of 2510, where she is subjected to propaganda and mental manipulation. She soon discovers that the women are there for their fertile eggs and the men for their sperm.
