When Ana Blackwood's friend goes missing, it's up to her and her sisters to make their first trip across Death Valley in their ramshackle old monster truck. It's an adventure and a death wish - one they've wanted to take for years. But they never imagined it would be under these circumstances, or that they'd be so ill-prepared.
They'll have to fight mythical monsters and terrifying challenges if they want to get across Death Valley in one piece and save their friend. Fortunately, they're up for the task!
