‘Oy! dean ya little tosser!
Dean Bovey, a psychotic and schizophrenic twenty-year old, lives with his terminally ill mum in a tower block council flat in Woodford Green, Essex. His father left when he was a baby, and so his grandfather, a war hero, took his mum on holiday, the only one she has ever had, to Lochnagar in the Scottish Highlands. She tells Dean that she wants to be buried there. Dean’s social worker, Chelsea Lawson, after two and a half years, convinces her sceptical colleagues that he is eligible to be taken off the Social Services Watchlist. Dean comes home from his menial job to find Mum has died, and so he nicks a car and tucks her up in the hatchback in her PJ’s and sets off for Scotland to fulfil her wish.
Chelsea arrives to carry out the ‘final interview’ but finds him and Mum gone, and assumes the worst, that Dean has killed her. She and the Police view the CCTV and see him dragging the body away and their fears are confirmed. The Police, led by D. I. Gett, thinks Chelsea knows where they might go. Chelsea is sacked, and in order to clear her name, sets off after them to Lochnagar, in order to find him innocent and clear her name and restore her career. DCI Gett pursues both parties, suspecting Chelsea knows where Deano intends to go.
