The Highway (2016)

Henley is on the last leg of his road trip home when he gets too tired to continue driving, so he stops at a remote motel for the night. Intending to just get a few hours of sleep, and be back on the road, Henley checks into the motel even though the power is 'temporarily' out. It is not until Henley tries to leave that he starts to suspect things are amiss and he must find a way out of there.
