In the desolate expanse of the U.S. desert, a decaying gas station run by the grizzled Vincent lures unsuspecting travelers into a web of depravity. When young freelancer Mark pulls in to refuel, he’s drawn into the station’s sinister underbelly—a hidden "bar" where pleasure takes a perverse turn. Meanwhile, a group of vibrant women—Naomi, a confident former cheerleader; Daphne, shy yet striking; Dylan, a free-spirited musician; and Ray, their writer mother—stop by on a road trip, unaware of the dark fate awaiting them. What begins as a routine pitstop spirals into a chilling encounter, as Vincent’s predatory charm and the station’s sordid secrets ensnare them all in a twisted game of power and submission.

As Mark explores the annex’s grim offerings, the women find themselves trapped in a nightmarish setup, their bodies exploited in a series of gloryhole-like cubicles designed for the pleasure of truckers and passersby. The remote station, surrounded by parked trucks and devoid of rescue for miles, becomes a claustrophobic stage for raw, unfiltered desires.
