The movie "The Silence of the Lambs" 1991

Clarice Starling, a young FBI trainee, must investigate a particularly difficult case: "Buffalo Bill", a cunning killer behind a series of murders, whose latest hostage is the daughter of a US senator. His victims are women, from whom, for unknown reasons, he removes pieces of skin. With her investigation going nowhere, the agent resorts to an unusual tactic: she seeks the help of Hannibal Lecter, a dangerous criminal who ate his victims. A psychopath and a psychiatrist by profession, Hannibal is the only one with useful clues about the killer on the loose. The fragile, ambitious young agent (Jodie Foster) and the obsessed monster strike a precarious bargain, even though they both know they can't trust each other.
