In a sunlit yet shadow-filled Los Angeles, private eye Philip Marlowe is hired by Orfamay Quest, a Kansas-born woman, to track down her brother, Orrin Quest. Marlowe begins by rummaging Orrin’s former hotel room and grilling a shady guest, Grant Hicks, only to stumble upon the dead desk clerk Haven Clausen, felled by an ice pick. The case twists quickly when Hicks phones Marlowe later, offering to have him guard something for a day or two. But when Marlowe reaches Hicks’s location, he finds Hicks dead with an ice pick buried in his neck. A masked, armed woman suddenly appears from behind him, clocks him with a blow, and flees into the night.
Recovering, Marlowe combs the room again and discovers a claim ticket for a roll of photographs. He tells the police what he can, but withholds the most crucial detail. A memory resurfaces: years earlier, a Brooklyn crime gang led by mobster Sonny Steelgrave had perfected a method of killing enemies with an ice pick—but Marlowe concedes the connection might be tenuous.
Marlowe’s pursuit leads him to the masked woman. She is television star Mavis Wald, and the photographs show her in a charged rendezvous with the mob boss Steelgrave, now moving his operation west. The case appears to hinge on a blackmail scheme, with the murders cascading from an initial attempt to extract money from Wald or her circle. Marlowe then tracks Wald, and in private hints to her that she may have been at the hotel to silence Hicks in exchange for the incriminating photos. Wald refuses his help, but Steelgrave’s men press harder—several try to intimidate, threaten, or buy Marlowe off, and one erudite henchman dies in the process.
Orfamay later reveals that her brother Orrin is staying at the clinic of Dr. Vincent Lagardie, a connection Marlowe already suspected. A plan forms: Marlowe arranges for Wald to cooperate, and a contract is secured with an executive from Wald’s hit TV show to work in Wald’s best interests. With Wald cleared of the murders and the clinic investigation underway, Marlowe presses Wald for the truth, and Orrin’s dark secrets start to emerge.
Marlowe confronts the clinic, where the doctor tranquilizes him with a drugged cigarette but does not harm him. Orrin stirs but dies after a final stab from an ice pick, and Marlowe discovers a photograph proving that Orfamay, Orrin, and Wald are siblings. This new information ties Orrin to the blackmail network and explains the cascade of killings—the plan that spiraled out of control. Marlowe endures his wound, tending it with Dolores Gonzales’s help, while burning the incriminating photos and negatives to protect Wald’s career.
Dolores arrives with Wald’s summons to Steelgrave’s home; Dr. Lagardie watches from afar as Marlowe and Dolores ride together. Marlowe learns that Dolores and Steelgrave had a complicated past, including a romance and a connection to Lagardie from Brooklyn years ago. Backstage at a nightclub, Dolores confesses the full truth—she had hoped to separate Wald from Steelgrave, driven by love for Steelgrave and a desire to shield Wald. Yet Wald’s career remains at stake, and Marlowe’s loyalty to the truth clashes with the need to protect the living.
Marlowe confronts Dolores in the club’s wings, and a tense exchange reveals that she was Orrin’s partner in the blackmail plot. He suggests she was also once married to Lagardie, deepening the web of ties. Dolores doesn’t back down, but as the confrontation unfolds, Lagardie arrives from a rear door. The two men acknowledge each other without incident, and Marlowe phones the police. Moments later Lagardie steps out and shoots Dolores dead, then turns the gun on himself, leaving Marlowe to depart before the police arrive.
In the aftermath, Marlowe has burned the photographs and resolved to keep Wald’s reputation intact, even as the case closes with a somber balance of truth, loyalty, and the costs of misused power. The city’s murky moralities linger, and Marlowe’s license hangs in the balance as Lt. Christy French pursues the possibility of disciplinary action, underscoring the fragile line between private inquiry and law enforcement.
