A young couple on a motorway journey are drawn into a game of cat and mouse with a truck driver following a near accident.
Tired and irritable, Zakes (Will Ash) and Beth (Christine Bottomley) drive home along the M1, a familiar journey full of harshly lit service stations and bad coffee. When a white truck narrowly avoids hitting them, its back doors open to reveal a woman terrified and screaming caged up inside. Unsure if what he has seen is real, Zakes calls the police but drives on. Beth is furious that he hasn't done more to help and at the next petrol station storms off. When she doesn't return, Zakes slowly realises that she too has been snatched by the white truck driver and is forced into a vicious game of cat and mouse with a ruthless killer who has terrifying plans for his human cargo.
