In Glasgow, Scotland, a motorcyclist (Jeremy McWilliams) retrieves an inert young woman (Lynsey Taylor Mackay) from the roadside and places her in the back of a van. A naked woman (Scarlett Johansson) dons her clothes, then goes to a shopping centre and buys clothes and make-up. She drives the van around Scotland, picking up men on the street. In a dilapidated house, she lures a man (Joe Szula) into a black void and he is submerged in a liquid abyss.
At a beach, the woman attempts to pick up a swimmer (Kryštof Hádek). Their exchange is interrupted by the cries of a drowning couple. The swimmer rescues the husband, but he rushes back into the water to save his wife and drowns. The woman strikes the swimmer's head with a rock, drags him to the van, and drives away, ignoring the couple's distraught toddler. Later that night, the motorcyclist retrieves the swimmer's belongings, ignoring the toddler, who is still on the beach.
The woman visits a nightclub and picks up another man (Paul Brannigan). He follows her into the void and is submerged in the liquid. Suspended beneath the surface, he sees the swimmer floating beside him. When he reaches to touch him, the swimmer's body collapses, leaving empty skin behind.
The woman seduces a lonely and sexually inexperienced man with facial disfigurement (Adam Pearson). After studying herself in a mirror, she lets him escape and drives to the Scottish Highlands. The motorcyclist intercepts the man and bundles him into a car, then sets out in pursuit of the woman with three other motorcyclists.
The woman abandons the van in the fog. She walks to a restaurant and attempts to eat cake, but retches and spits it out. At a bus stop, she meets a man (Michael Moreland) who offers to help her. At his house, they eat, watch television and listen to music. Alone in her room, she examines her body in a mirror. She visits a ruined castle with the man and they kiss. At his house, they begin to have sex, but she stops and examines her vagina, alarmed.
The woman wanders in a forest and takes shelter in a bothy. She is woken by a commercial logger (Dave Acton) molesting her. After she runs into the forest, he catches her and attempts to rape her. In the struggle, he tears skin from her back, revealing a black, featureless body. As the woman extricates herself from her skin, the logger douses her in fuel and burns her alive.
