Set in the South Seas, Seven Sinners stars Marlene Dietrich as a cabaret singer whose reputation as a troublemaker has gotten her kicked out of one port of call after another. Once more causing a riot, Dietrich takes refuge on the first ship out, together with her underhanded cohorts Broderick Crawford and Mischa Auer. During her next stopover at the Seven Sinners Cafe, Dietrich meets handsome Naval officer John Wayne. He falls in love with her, much to the consternation of island governor Samuel S. Hinds, who knows that any romantic entanglement with Dietrich invariably results in dissension, disarray and brawls. He tells her to lay off Wayne or shell be deported. But Dietrich insists upon performing one last song for the Duke...and sure as shootin, a battle royal ensues. This time, however, Wayne works tirelessly behind the scenes to solve everyones problems. Maintaining the fascination level of Seven Sinners is a limitless array of top character actors, including Oscar Homolka, Billy Gilbert, Albert Dekker and Reginald Denny. The film was remade in 1950 as South Sea Sinner, starring Shelley Winters and--are you holding on to something?--Liberace. ~ Hal Erickson, All Movie Guide
