On New Year’s Eve in 1923, the editor of the New York Chronicle sits waiting for news about a daring theft: legendary jewelry once owned by Mrs. Reginald Thorndyke, a bracelet valued at roughly $50,000. The suspense isn’t just about the value; it’s about the man who may have pulled it off and the life he might be living after the crime. Detective Tom Gaynor [Preston Foster] discovers the truth in a twist that reframes the whole case: the thief is none other than the notorious Harry Melton [Brian Donlevy], a.k.a. the Heliotrope, so nicknamed because he always wears a heliotrope flower in his jacket lapel. The scent of danger and romance tangles with a looming sense of sympathy as the case unfolds.
Harry’s partner and lover, Flo Melton [Miriam Hopkins], is moments away from giving birth in a hospital when Harry arrives with a bracelet—the gift of a complicated, if misguided, love. Tom Gaynor believes that beneath Harry’s criminal reputation there lies a fundamental decency, a man possibly pulled off course by harsh circumstances. This belief drives Gaynor to offer help, and he warns Harry that an Insurance Companies Protective Association reward awaits anyone who can bring the bracelet back and reveal the thief’s true path. Harry denies any involvement in the theft and insists he intends to become a better man now that he is about to become a father.
The dynamics of trust are complicated by Flo’s own longing. She doesn’t want to leave the urban life behind, doesn’t want to embrace country living or lawful citizenship, and has different goals for their future. Meanwhile, Harry’s male partner Eddie [Phillip Reed] is a volatile presence who would rather partner with Flo than with him. Sensing the crumbling edges of their cooperation, Harry agrees to one final job—a jewel heist at a socialite party hosted by Pamela Cartwright—before attempting to go straight.
The plan is threatened when Eddie tries to frame Harry after the theft. Harry manages to conceal the stolen jewelry just as Gaynor arrives to question him, foiling Eddie’s scheme. In the wake of these revelations, Harry discovers that Flo and Eddie are more than just collaborators; they are romantically involved. A volatile confrontation erupts, ending in Harry shooting Eddie. In the aftermath, Harry tells Flo he will end her efforts to see their daughter, Diana.
In a heavy, sustained decision rooted in protection, Harry turns himself in to the police for the sake of Diana, and the newborn child—Diana Melton [Sharon Douglas]—is placed in Gaynor’s custody, where she remains for many years while Harry serves his sentence. Over time, Gaynor rises in the ranks to become a Supreme Court Justice, and Flo uses Diana’s future as a tool to press Gaynor into helping her. The family saga expands beyond the courtroom as Flo attempts to maneuver Diana’s life to her advantage.
While Harry remains imprisoned, he learns, through a pal [Harold Huber] known as Stubby, that Flo intends to exploit the situation. Determined to protect his daughter, Harry escapes and begins a desperate search for Flo. The pursuit leads him to Flo’s hotel room, where she is allied with Enzo Calibra [Douglass Dumbrille], one of her accomplices. A fierce brawl erupts, and Enzo’s own bodyguard accidentally kills him, allowing Flo to slip away. Harry corners Flo, and in a life‑altering moment, she loses her balance and falls to her death from a balcony.
The story closes with a poignant, patient acknowledgment of time and memory. Diana’s wedding is announced years later, and to mark the occasion, Harry sends a box of heliotrope flowers—his favorite—continuing to honor a symbol that began his notorious journey.
