The First Deadly Sin (1980) is a dark, slow-burning crime thriller that marked the final film appearance of one of Hollywood’s most iconic actors, Frank Sinatra. Directed by Brian G. Hutton and based on the novel by Lawrence Sanders, the film blends police procedural storytelling with a deeply personal drama about aging, mortality, and obsession.
Although it didn’t become a major hit upon release, the film has developed a reputation as an atmospheric late-70s detective story with a haunting tone and a melancholic performance from Sinatra.
Detailed Summary
A Brutal Murder Shocks New York
The film opens in New York City with the discovery of a horrifying murder. A woman has been killed with a strange, homemade weapon designed to crush her skull with a powerful bolt-like impact. The method is unusual, brutal, and extremely precise.
Veteran NYPD detective Edward X. Delaney (Frank Sinatra) is assigned to investigate the case. Delaney is an experienced homicide detective nearing retirement, known for his persistence and methodical approach.
At the same time, Delaney’s wife Barbara is gravely ill and hospitalized, creating emotional strain as he divides his time between the hospital and the investigation.
The Killer Strikes Again
Soon after the first murder, another woman is killed using the same bizarre weapon. The murders appear random, which makes the case even more frustrating.
Delaney studies the crime scenes obsessively. The killer leaves almost no evidence, no fingerprints, and no clear motive. The weapon itself is strange enough to become the key clue.
As Delaney interviews suspects and studies patterns, the investigation moves through various parts of New York’s social landscape—from bars and apartments to laboratories and hospitals.
Meanwhile, the audience learns the identity of the killer early in the film: Daniel Blank, played by Bruce Dern. Blank is a lonely, quiet man who works in a laboratory environment. He carefully constructs a mechanical murder weapon designed to deliver a deadly blow to the head.
The tension of the film doesn’t come from discovering who the killer is, but from whether Delaney can prove it.
Delaney’s Obsession with the Case
Delaney becomes increasingly obsessed with solving the murders. His colleagues notice that the case is consuming him.
At the same time, his wife’s condition worsens. Delaney visits her at the hospital whenever he can, but he feels helpless watching her slowly decline. These scenes give the film a heavy emotional weight.
The investigation eventually points Delaney toward Blank after he identifies the unusual metal and mechanical components used in the murder weapon. Blank has the knowledge and access needed to construct it.
Closing in on the Killer
Delaney begins quietly surveilling Blank, studying his routines and behavior. However, the detective lacks enough evidence to arrest him.
Blank grows paranoid, sensing he may have attracted police attention. Yet he also seems compelled to continue killing.
Eventually Delaney gets the break he needs when he finds enough evidence tying Blank to the murder weapon and crime scenes.
Movie Ending
The final act brings the investigation to its inevitable confrontation.
Delaney finally gathers enough evidence to arrest Daniel Blank for the murders. The killer is taken into custody, and the case that consumed the detective for so long is officially solved.
However, the emotional resolution of the film lies elsewhere.
Throughout the investigation, Delaney had been visiting his wife Barbara in the hospital as she struggled with a serious illness. Her health steadily declines during the course of the movie.
After the arrest, Delaney returns to the hospital and discovers that his wife has died.
This moment lands with quiet devastation. The case that had absorbed his entire focus is over, but the personal loss he had been trying to emotionally postpone now fully hits him.
In the final scenes, Delaney walks alone through the hospital and then into the city. The film ends on a somber note, emphasizing the idea that solving crimes cannot protect detectives from the tragedies of their own lives.
The ending highlights the central theme of the story: the relentless nature of death and the emotional toll of a life spent chasing violence.
Are There Post-Credits Scenes?
No. The First Deadly Sin does not include any post-credits or mid-credits scenes. Once the film ends, the story is complete.
