Dick Tracy (also known as Dick Tracy, Detective) is a 1945 American film noir pulp action film based on the Dick Tracy comic strip created by Chester Gould. The film is the first of four installment of the Dick Tracy film series, released by RKO Radio Pictures.

Plot
Dick Tracy (Morgan Conway), a supremely intelligent police detective, must solve a series of brutal murders in which the victims, all from different social and economic backgrounds, are viciously slashed to pieces by the one known as Splitface (Mike Mazurki).
