A family’s idyllic outing descends into terror when high school teacher Hoaggie, his wife Jill and stepsons Maika and Jordon go exploring an isolated coastline. But an unexpected meeting with a pair of murderous drifters thrusts the family into a nightmare road trip. At first the family’s terror seems to be born of a random encounter with two sociopaths who seem intent on god only knows what. But as the night drags on Hoaggie and Jill realize that this nightmare has been set in motion 20 years earlier.
