A carefully planned heist on a suburban bank goes awry when the gang of three small-time criminals are interrupted by the unexpected arrival of two nattering cleaners. Taut as a drum, Vernon Sewell’s suspense thriller is an outstanding example of the lean British ‘B’ film. A carefully planned heist on a suburban bank goes awry when the gang of three small-time criminals are interrupted by the unexpected arrival of two nattering cleaners. The gang lock the bank manager and his secretary in the airtight vault and make off with the cash. However, they soon realise that the pair will suffocate, and the gang will face a murder rap if they can’t free them. With only 12 hours’ worth of air in the vault, the clock is ticking. The film counts Quentin Tarantino, Martin Scorsese and Edgar Wright amongst its fans and is presented here in High Definition for the first time anywhere.
