In Glasgow, a motorcyclist retrieves an inert young woman from the roadside and places her in the back of a van, where a naked woman dons her clothes. After buying clothes and cosmetics at a shopping centre, the woman drives the van from town to town, picking up men. She lures a man into a dilapidated house. As he undresses, he follows the woman into a void, seemingly unaware of his surroundings, and is submerged in a liquid abyss.
At a beach, the woman attempts to pick up a swimmer, but she is interrupted by the cries of a drowning couple attempting to rescue their dog, as it is pulled out to sea. The swimmer rescues the husband, but the husband rushes back into the water to save his wife, and both drown. As the swimmer lies exhausted on the beach, the woman strikes his head with a rock, drags him to the van, and drives away, ignoring the couple's distraught baby. Later that night, the motorcyclist retrieves the swimmer's belongings and tent, ignoring the baby, who is still on the beach.
The woman visits a nightclub and picks up another man. At the house, he follows her into the void and is submerged in the liquid. Suspended beneath the surface, he sees the swimmer floating naked beside him, alive but bloated and almost immobile. When he reaches to touch him, the swimmer's body collapses, leaving his skin. A red mass empties through a trough.
The next day, the woman receives a rose from a street vendor, purchased by another man in traffic. She listens to a radio report about the missing family from the beach. The woman enters a dark room and is examined by the motorcyclist. She seduces a lonely man with facial tumours but lets him leave after examining herself in a mirror. The motorcyclist intercepts the man and bundles him into a car, then sets out in pursuit of the woman with three other motorcyclists.
In the Scottish Highlands, the woman abandons the van in the fog. She walks to a restaurant and attempts to eat cake, but retches and spits it out. In a bus, she meets a man who offers to help her. At his house, he prepares a meal for her, and they watch television. Alone in her room, she examines her body in a mirror. They visit a ruined castle, where the man carries her over a puddle and helps her down some steps. At his house, they kiss and begin to have sex, but the woman stops and examines her genitals.
Wandering in a forest, the woman meets a commercial logger and shelters in a bothy. She awakens as the logger is molesting her. She runs into the wilderness, but he catches and attempts to rape her. During the struggle, he tears her skin, revealing a black, featureless body. The man panics and flees. She holds her peeled off face in her hands where it still moves and blinks at her. As the woman extricates herself from her skin, the man returns and douses her in fuel and burns her alive. Elsewhere, the motorcyclist stands on a mountaintop alone and looks out across a snowy field. The woman’s smoldering remains are shown as her ashes rise up in smoke and slowly descend to the ground.
