Ziggy Brennan grows up under the flamboyant, neglectful care of her mother Natalie, learning to hustle men and pick up street smarts from the wild crowd they frequent. An older con, Denny Reagan, mentors her in his crooked trade. One night she encounters the honest sailor‑farmer Martin “Mart” Neilson, and they fall in love. While Mart is away fighting in the war, Ziggy learns she is pregnant.

On Mother’s Day 1946, Ziggy Brennan, Mona Freeman, looks back on her life with a quiet gravity that hints at the storms she’s weathered. Eight years earlier, her vain and corrupt mother Natalie Brennan, June Duprez, asks Ziggy to pretend they are sisters, and the two begin a duplicitous pattern that uses men for money. Ziggy secretly takes a liking to a fellow con artist, Denny Reagan, James Dunn, and even steals a sailor’s watch that Denny admires. The inscription on the watch—revealing it was a gift from the boy’s mother—gnaws at Denny’s conscience, and Ziggy, perhaps moved by a glimmer of honesty, returns it to Mart Neilson, William Marshall, the sailor who later becomes a central figure in Ziggy’s life. Mart invites Ziggy on a date, and their connection deepens into marriage, even as war thunders on the horizon.
Two days after their wedding, Mart is shipped off to battle, and Ziggy discovers that she is pregnant with their child. The news should be a bright turn, but Ziggy’s joy is shadowed by Natalie’s warnings about Ziggy’s capability as a mother. The birth brings Martha, a baby whose well-being hangs in the balance as Ziggy and Natalie clash over responsibility. Ziggy’s life as a caregiver becomes precarious: she leaves Martha with a reckless young babysitter, and Martha narrowly escapes danger when the babysitter and the girl she’s with slip away, allowing Martha to slip from the crib. A judge’s decision, based on the babysitter’s testimony, places Martha in a juvenile ward, and Ziggy receives a suspended sentence for child neglect, with the harsh condition that she may not contact her child. Ziggy’s troubles are compounded by family pressure; Denny Reagan’s mother, Dorothy Vaughan, tracks Ziggy down and urges her to pray for salvation, underscoring the moral weight bearing down on Ziggy’s choices.
As Denny completes his sentence and returns to civilian life, he emerges a reformed man. He finds Ziggy again and learns that she has taken in an abandoned infant she found in a local church, caring for the child with a quiet, steadfast devotion and naming him Denny. This reunion marks a turning point: the two reunite publicly as a family and, together, appeal to the court for a second chance. The film’s heart lies in their shared determination to build a stable life for two children who have found their way into their care, and in Ziggy’s willingness to redefine motherhood and love in the face of past missteps. In the end, Ziggy and Denny leave the world of schemes behind, stepping forward as a united family, ready to face whatever comes next with a newfound resolve and the fragile hope of a fresh start.
