Anyone who’s ever taken a long road trip knows the moment: You pull into a random gas station or rest stop — tired, hungry, desperate for a bathroom — and what greets you is a scene straight out of your worst nightmares. Filthy floors, broken faucets, the unmistakable stench of neglect. But what if that unsettling experience was just the beginning of something far more sinister?

That’s the premise behind the aptly titled horror flick “Rest Stop,” a gritty B-grade film that turns the familiar discomfort of roadside travel into a full-blown horror show. When two rebellious teens run away to Los Angeles, they make the fatal mistake of pulling into a rest stop that’s become the stalking ground of a deranged killer — a death trap decades in the making.
