James Curtayne was once a highly successful prosecutor and district attorney in New York City, known for his sharp legal mind and relentless pursuit of justice. However, his career took a downward turn due to his struggle with alcohol, which ultimately forced him out of the high-pressure world of criminal law. After a long period away from the courtroom, he attempts to settle into a quieter, less demanding practice in civil law, hoping to approach a long-overdue retirement. Despite his efforts, the shadows of his past and the toll of aging begin to weigh heavily on him.
The story takes a personal turn when a boy from Curtis’s old neighborhood, Johnny O’Hara, is accused of murder. Johnny, a young man with a troubled past, finds himself at the center of a criminal investigation that threatens to upend everything. His parents, desperate and unable to afford legal help, turn to Curtayne, pleading for him to take the case. Though he is reluctant, knowing the difficulty and emotional toll involved, Curtayne accepts, understanding the case might be more than just a professional challenge—it could become a personal battle as well.
The investigation begins with the murder of Johnny’s boss, Bill Sheffield. Sheffield was shot and robbed at his home during the night, with witnesses seeing a two-tone, older-model coupe leaving the scene. A witness exiting a saloon from a distance provides crucial information, helping police trace the car to Johnny. When questioned by Detective Vincent Ricks [pat-obrien] and District Attorney Barra [john-hodiak], Johnny panics and tries to flee, claiming he believed the detectives were threats after him. The evidence soon mounts, revealing that Johnny’s fingerprints were on the murder weapon, which he claims was stolen along with his car.
Johnny’s defense is further complicated when Pete [Korvac] — a young man with a reputation for dishonesty — is brought in. Pete confesses that he was the driver and implicates Johnny as the one who fired the gun. Johnny admits he had a fight with Sheffield over unpaid overtime that day but insists he was working all night as his alibi, which is later discredited by the night watchman. The real story is more complicated: Johnny was breaking up with Katrina, the wife of a notorious mobster called “Knuckles” Lanzetta, who controls the waterfront. Fearing repercussions, Johnny lies to protect Katrina, knowing that revealing the truth about their relationship would put her in danger.
Curtayne, a widower, is cared for by his devoted daughter, Virginia Diana Lynn. She has sacrificed her own future with her fiancé Jeff to ensure her father stays sober. Despite her concern, Curtayne believes he can manage the pressure, but his old age and drinking habits start to undermine his confidence. As he delves into the case, he visits Johnny’s family and Knuckles Lanzetta, trying to find out the truth behind the crime. The Korvac family dismisses him, denying any involvement of Pete, while Lanzetta’s denials seem evasive. Curtayne also questions Lanzetta but is cautious about accepting his offers of assistance, wary of the influence of organized crime.
During the trial, Johnny’s alibi crumbles, and Pete’s evasive testimony appears convincing. Curtayne begins to doubt his own abilities, feeling increasingly overwhelmed and sensing his mental decline. His reliance on alcohol intensifies, and he makes a risky decision to bribe a Norwegian seaman named Sven Norson, who offers to change his story for $500. When District Attorney Barra uncovers the bribe, he quietly reveals it to Curtayne, who is already doubts about his steadiness. Despite the mounting evidence and corruption, Barra secures a conviction, and Johnny faces the electric chair, with Curtayne on the verge of disbarment due to his questionable conduct.
Realizing that Johnny might have been framed, Curtayne and Ricks revisit the case, seeking a motive that could explain the true killer. They examine the “gold bar” story—an attempt to link the victim to stolen narcotics destined for the Chicago mob—only to find the tale unconvincing. Instead, lab tests reveal that the battered suitcase Johnny’s car carried contained $200,000 worth of narcotics, indicating a larger criminal enterprise. To catch those responsible, Curtayne devises a plan to infiltrate the criminals’ operation by planting a lookout at the scene. He volunteers to deliver a suspicious-looking suitcase, wired for sound, in hopes of catching the real culprit.
The plan leads to a trap set by Johnny’s brothers, who are revealed to be involved in the scheme. The eldest brother, James Korvac, confronts Curtayne, revealing that firm ties to organized crime run deep. Tragically, the situation spirals out of control when Curtayne is abducted, marched toward the river with the suitcase in hand, and faced with certain death.
The police, led by Barra [john-hodiak], quickly organize a dragnet but arrive too late. A gunfire exchange ensues, resulting in the death of Curtayne—heroically sacrificing himself to protect the truth. Moved by his bravery, Barra is faced with a difficult decision: to pursue justice at all costs or to honor Curtayne’s final act of courage. Before Ricks can respond, an ambulance medic reports that Curtayne has succumbed to his wounds, leaving his fate and the justice he fought for hanging in the balance.
Throughout this story, themes of redemption, sacrifice, and the corrupting influence of organized crime intertwine, painting a complex picture of a man trying to reconcile his past with his desire to do right. The film underscores the human cost of the relentless pursuit of justice and the fragile nature of morality in a corrupt world.
