'The Informers' sees Scotland Yard battle organised crime in this tough 1960s drama, a forerunner to the 1970s TV series 'The Sweeney'. Following a number of high profile robberies, Superintendent Bestwick (Harry Andrews) decrees that his officers should adopt new scientific police methods and Chief Inspector Johnnoe (Nigel Patrick) is ordered to break contact with his network of snouts. However, when his best informant Jim Ruskin is murdered whilst on the trail of the gang responsible for a number of bank robberies, Johnnoe follows his detective instincts rather than orders. Following up Jim's earlier tip off, Johnnoe encounters two mobsters, Bertie Hoyle (Derren Nesbitt) and his wily cohort Leon Sale (Frank Finlay). When Hoyle's attempt to bribe Johnnoe fails the criminals fit him up with the help of Maisie, a cheap tart. Having been suspended, but released on bail, Johnnoe again ignores orders as he attempts to clear his name. With the help of the Ruskin family he tries to track down the murderers of his informer, solve the robberies and gain revenge on the criminals who framed him.
