When three young, married couples decide to get away from it all and take a two-week summer vacation in northern California's Yolla Bolly Wilderness, they are not prepared for the impact this trip will have on their lives.
Filled with expectations of high adventure, Larry and Shannon Larsen, Tony and Caitlin Salerno, and Eric and Elaine Taylor leave their familiar world behind and enter a remote, new environment fraught with unimaginable dangers. Their guided trek on horseback through the forested mountains brings them into contact with drug traffickers and an Indian tribe possessing incredible powers. In this primitive setting, far removed from the laws of civilization, the travelers discover that most people, including themselves, revert to the most basic of instincts.
Confronted by the darker side of human nature, they learn a great deal about themselves, their relationships, and love. None of them will be the same person they were before they embarked on this adventure. Their lives have been changed forever by events and powers beyond their control.
