Brighton sculptor Vonnie Sharpe's laidback routine is shattered when her flatmate Gina is carjacked during a bank robbery.

Gina's car is found abandoned on the South Downs but there's no sign of the quiet young chip shop worker. A worried Vonnie enlists the help of her arty friends in the race to find her. With a singer, actor and busker on her team, she half-wonders if she could've got Arts Council funding for her search.

Vonnie tracks down the bank robber, who insists he left Gina unharmed in her car. From here the trail twists and turns through art classes, language schools and escape rooms, as she narrows down her list of suspects. A ransom note arrives and it's Vonnie who the kidnappers want to deliver the money. With the cash drop imminent and not knowing who she can trust, she needs to find answers - and quickly.
