Pauline thinks she's going on an ordinary vacation, but instead finds the most thrilling and dangerous adventure of her life...and one very handsome young Marine.

Pauline is supposed to be a new college graduate, but after a very embarrassing incident at college, she leaves school and returns home. She's also dealing with her younger sister's suicide. To fulfill her sister's dream, Pauline goes on a summer rafting trip in the wilderness of British Columbia, Canada, though she's not as outdoorsy as her sister was.

Once Pauline starts the journey down the river, returning to civilization proves rife with unexpected and treacherous obstacles. She soon finds herself trapped with her river guide, Ellis, a young Marine who harbors his own dark secrets. The pair start off not liking each other.

Things take a turn for the worse when they begin to suspect they are being followed, and Pauline is the target. As they make their way down the river in a race against time, they have to work together to outsmart her potential killers.
