The story is inspired by the disappearance in the late 80's of a North American couple who disappeared in the West Australian desert on a 4WD holiday. They were never seen alive again. Their abandoned vehicles and totally unused supplies were found in sand dunes near an Aboriginal sacred site--less than an hour away from the closest town. Two years later, the two men were both found dead of natural causes, on the same day, 1000 miles apart back in North America.

Prey tells the story of 3 couples who set out into the same desert and unluckily end up in the same area, at the same time of year, with disastrous results. The previously unrevealed psychological and sexual liaisons the couple's had secretly shared come to light as there lives end one-by-one. Who will survive?
