The Unsuspected (1947) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of The Unsuspected (1947), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

In the quiet suburban New York home of Victor Grandison, Claude Rains embodies a shadowy figure who murders his secretary, Roslyn Wright Barbara Wooddell, and leaves her body hanging from a chandelier, with the death officially logged as a suicide. A week later, Victor is on air as the host of his popular radio show, The Unsuspected, a program that dives into real-life darkness even as his own world begins to unravel. At the same time, his niece Althea, Audrey Totter, throws a surprise birthday party for him, trying to lift his mood after the double blow of Roslyn’s death and the disappearance (reports say sinking) of his wealthy ward, Matilda Frazier Joan Caulfield. Oliver Keane Hurd Hatfield, Althea’s husband and ex-fiancé to Matilda, sits with a bottle in hand, while a mysterious visitor named Steven Francis Howard Ted North arrives, claiming to have been Matilda’s husband.

After the party, Homicide Chief of Detectives Richard Donovan Fred Clark lingers with Victor, sharing a thick file on a separate hatchet-murder case and forcing Victor to confront the uneasy overlap between fiction and truth. Donovan’s presence coincides with Victor’s tense first meeting with Steven, and the plot thickens as Matilda’s vast estate looms over every decision. A cable from Rio de Janeiro confirms Matilda is alive and en route, jolting Victor into new calculations. Althea hovers near the center of power, and Victor starts to sense a larger web closing in around him. The next twist arrives when Victor learns that Matilda is indeed alive and set to arrive the following day, opening a fresh set of questions about loyalty, money, and truth.

Matilda boards a Pan American plane in Rio and begins her return to the United States. Steven accompanies her to the airport and a bar afterward, where he tells her they were married. She insists she has no memory of him, despite a marriage certificate and a visit to the judge who performed the ceremony. Back at the Grandison house, Victor’s world grows more perilous as Press [Jack Lambert], a killer whose identity Victor has unearthed but kept under wraps, menaces him. Victor silences the threat by playing back the confession he recorded earlier, turning Press into a loyal henchman who can be used to do Victor’s bidding.

Steven and Matilda arrive at Victor’s house; Matilda, wary and guarded, wishes to go straight to her room, only to find Althea occupying it under the pretense that Matilda “wasn’t coming back.” After a brief exchange, Matilda is allowed to bathe and regroup. Victor and Steven debate how to handle Matilda’s amnesia about their supposed marriage, and Victor decides to keep Steven under observation in the guest house for the time being. Then Jane Moynihan [Constance Bennett]—Victor’s producer who has been watching closely—enters, and the two of them cross paths with Oliver as they weigh the strange truth behind Roslyn’s death.

The investigation heats up as Steven gives Donovan new information—Roslyn’s death appears to be a murder, connected to a phone call she received just before dying, and a caller who hung up. Althea, who had been on the line with Roslyn at the time, suspects Victor’s ever-expanding control—yet she stays quiet, fearing the loss of Matilda’s fortune. In a brutal turn, Victor records a quarrel between Althea and Oliver and gently nudges Oliver to leave; then, confessing to Roslyn’s murder, he shoots Althea dead. With Matilda and Steven as witnesses, Victor uses the audio recordings to frame Oliver, and the police close in as Oliver’s brakes fail in a sabotaged car.

Jane’s efforts to bring Steve and Matilda closer are complicated by Victor’s web of deception, and Matilda remains wary of Victor’s manipulation even as she is drawn deeper into his world. Victor’s plan advances toward a dangerous climax: he intends to kill Matilda, using lines he has drafted for his radio show as a supposed script, and he instructs Press to carry out the broader coup. Steven uncovers the recording Victor has used to frame Oliver and calls Donovan, but the call is cut short when Victor returns and intercepts the line. Press drags Steven away, shoving him into a trunk and driving off toward a trash incinerator, while the district’s police race to intervene before the trunk meets its fiery fate.

Donovan and the officers arrive just in time as the incinerator roars to life, and the investigators manage to halt the process before the trunk is destroyed. The drama shifts to the broadcast booth, where Victor attempts to resume his show and maintain control of the narrative. Donovan storms the control room, and the audience is stunned as the truth unfolds on the air. Matilda and a battered Steven watch from the auditorium as Victor’s carefully constructed façade begins to crumble under the weight of his own confessions. In a final, chilling reveal, Victor confronts the truth of his own identity on air.
