This pilot TV movie heralded the iconic and classic British TV series The Sweeney which ran from 1974 to 78. This film set the standard for the series with it's location filming, violent depiction of the London underworld and the realism of the police in the 1970s. John Thaw in the title role is a Detective Inspector in the Metropolitan Police Flying Squad, he finds modern team working practices difficult as he's used to following his own instincts. When one of his men is brutally murdered Regan is determined to find out who did it despite being ordered to leave it to the Murder Squad. He seeks out his former Sergeant George Carter (Dennis Waterman) to help him and soon they are embroiled in an organised gangland takeover where loyalties change very rapidly. For anyone who loved the TV series or who remembers the 70s well this is a great nostalgic film, very realistic, brilliantly written and a film that deserves a modern audience.
