Lucas and Hope are on the adventure of a lifetime. They're archaeology students spending their summer trekking through the Amazon rain forest with a team of researchers in search of a long lost civilization. Miraculously they find it, but unfortunately for them they awaken an ancient power that forces them to switch bodies!

With the help of a sexy Brazilian historian and a seductive french linguist they must uncover the secrets of this long forgotten people before it's too late. But that doesn't mean they can't have a little fun along the way. As college students Lucas and Hope know there's nothing more important than experimenting.
