Ginger Ted Charles Laughton is an Englishman and a dissolute beachcomber living on a sun-washed Dutch possession somewhere in the Indian Ocean, where his only true companion is his loyal dog Dudley. When a ship makes its monthly visit, he must outrun a mob of creditors to claim his remittance cheque from the Controleur Robert Newton, the stern colonial governor who keeps the islands in line. A well-meaning friend squeezes him for debts, leaving Ginger with barely anything to spare, but the sting of obligation still gnaws at him.
Ginger then gets Lia Dolly Mollinger to slip out of the classroom of Martha Jones Elsa Lanchester, a homesick man eager to speak of England. He spins stories to Lia about home, and in response, Martha’s stern, moralistic world tightens around him. Martha, unmoved by his charm, has him arrested, setting off a chain of consequences that drag Ginger into a reformist program he never asked for.
Sentenced to three months on the road gang, Ginger’s fate looks bleak, but the puritanical Martha Jones and her missionary brother Dr Owen Jones Tyrone Guthrie insist on deportation. Yet Ginger is the Controleur’s only real local friend, and the governor orders him sent to the alcohol-free Agor Island in a bid to reform him instead of simply casting him out.
When Martha insists on traveling to another island to tend to a medical emergency, the Controleur dispatches his sergeant J. Solomon as escort, with secret orders to fetch Ginger on the return trip. A storm of misfortune follows: the boat’s propeller rips a reef, forcing the party to spend a tense night on the nearest island while repairs are done. At first, Martha finds the experience harrowing, but the close proximity and shared peril begin to soften her disposition toward Ginger. After Dr. Jones publicly thanks Ginger for not taking advantage of his sister, Ginger lashes out and knocks the Controleur down when the governor mocks him, demonstrating the rough edge still beneath his charm.
While Ginger lies unconscious from drink, Martha quietly tends to his shack, cleaning and mending until he staggers back. He confronts her, and in a charged moment, demands she leave his space. The tension between them deepens, flickering with unexpected vulnerability.
Then a typhoid outbreak hits another island. The Controleur asks Ginger to accompany Dr Owen Jones to inoculate the natives; Ginger balks at first, then relents when Martha’s resolve and insistence grow harder to resist. But when Jones is struck by a malaria flare-up, Martha insists on stepping into his role. Ginger wavers, but the sight of her crying finally pushes him to change his mind.
On arrival at the village, the locals blame the disease on abandoning their old religion, and Albert [D.A. Ward], the headman and a former Christian convert, warns them to leave. Martha presses forward to confront the villagers, but Ginger physically shields her and pulls her away from danger. The headman’s wife brings a sick child to them, and Martha inoculates the child that very night. When the headman demands his child back, Ginger steadfastly sends him away as ominous drums echo the oncoming threat.
Facing an imminent attack, Ginger reflects on his past—a longing to marry a barmaid and run a pub, tempered by the memory that he’s the son of a local vicar—while Martha opens up about her own father’s self-made ruin. The confrontation dissolves into quiet resilience as the child recovers, and the danger finally passes.
In the aftermath, the pair chooses a shared future: they marry and return to England to manage a pub, with Ginger choosing sobriety and a quieter life. The island’s trials temper his appetite for reckless freedom, guiding him toward a steadier, more hopeful path—and a life back in England that promises companionship, responsibility, and a sense of home.
