The early years of World War II is the setting for this action comedy starring Burt Lancaster, Virginia Mayo, and Chuck Connors (his biggest role to date). Directed by Arthur Lubin, it features an Edwin Blum screenplay from a William Rankin-Stanley Shapiro adaptation of William Rankin's play.
Lancaster plays Master Gunnery Sergeant James O'Hearn, whose court martial trial has just begun (Hayden Rorke plays the prosecutor and Cliff Clark is among the officers who sit in judgment). After a series of outlandish sounding charges are read, O'Hearn declines the opportunity to defend himself. However, his court appointed attorney (Bob Sweeney) will mount a defense anyway. A series of witnesses recall the events that lead to the charges, and flashbacks are used to tell their stories.
Ginger Martin (Mayo in the title role) was a displaced showgirl in Southeast Asia that Marine Private Davey White (Connors) was to marry before his Sergeant and mentor O'Hearn intervened. A barroom brawl and their ensuing fight causes the men to miss their ship on its way to sea. Further circumstances keep the AWOL Marines, with Ginger in tow, from returning right away. In fact, for months they are stranded on a remote island commanded by Vichy French sympathizer Pierre Marchand (Leon Askin).
After enjoying the pleasures of hotelier Lillie Duval (Veola Vonn) and her girls, O'Hearn learns that Dutch Captain van Dorck (Rudolph Anders) is really a Nazi that's been placing radar equipment throughout the South Pacific. He then frees or convinces the real deserters, who have made the island their home (including Arthur Shields), to join his plan to steal van Dorck's yacht, after which they discover and disrupt a Japanese invasion fleet by attacking it!
The details of the battle and the outcome of the trial are intertwined; Strother Martin appears as a spectator.
