 Still struggling to accept her fiancé s death in a rock climbing accident, mountain guide DIANA PENNINGTON gratefully accepts industrialist CURT SEAVER s offer to find the body using a new satellite imagery technology his company has developed. But while traversing the legendary "Snowman s Pass" with Curt and his companions HUGO and TYLER, Diana is horrified to discover the search for her fiancé is a decoy; they are in fact hunting for a fallen spy satellite, property of an enemy foreign power. Barely escaping with her life, Diana finds herself pursued through the cold and threatening mountains in a deadly cat and mouse game, with only a backpack full of climbing gear and her instincts to defend herself against the dangerous, and increasingly desperate men.
