LOVE CAN HURT. BETRAYAL CAN KILL.

Shattered by the discovery of her husband's affair, Liv knows they need to leave the chaos of New York to save their marriage. Maybe the road trip they'd always planned, exploring America's national parks - just the two of them - would help heal the wounds.

But what Liv hasn't told her husband is that she has set him three challenges on their trip - three opportunities to prove he's really sorry.

If he fails? Well, it's dangerous out there in the wilderness; accidents happen all the time.

And if it's easy to die, then it's also easy to kill.
