John Coniston is the manager of a cash counting house - a man so scrupulous he replaces stolen cash with his own money. When he confronts security guard, Chris, and forklift driver, Marcus, over a missing £50,000 - they expect their cautious boss to call the police, but he is about to offer them a way out... Together these disillusioned men - John, desperate for some adrenaline in his humdrum existence; Chris, eager to fund a new life with his young Polish girlfriend and Marcus, desperately in debt after losing money in his wife's hairdressing business - plan the perfect heist. But these are no seasoned criminals, just three ordinary men... Can they cope with the pressures of a big-time job?
