The Big Sleep (1978)

In 1970s England, private detective Philip Marlowe is asked to the stately home of General Sternwood, who hires Marlowe to learn who is blackmailing him. While at the mansion, he meets the general’s spoiled and inquisitive daughter Charlotte and wild younger daughter Camilla.

Marlowe’s investigation of the homosexual pornographer Arthur Geiger leads him to Agnes Lozelle, an employee of Geiger, and to Joe Brody, a man that Agnes has taken up with. He also discovers Camilla at the scene of Geiger’s murder, where she has posed for nude photographs, and takes her home safely to a grateful Charlotte.
