Metropolitan Pictures' Port of Hate was directed by one of the studio's two chief executives, Harry S. Webb (the other, Albert Ray, was presumably busy on the company's Bob Steele western series). The story takes place on a faraway island (probably nearby Catalina), where soldiers of fortune Bob (Kenneth Harlan) and Don (Carleton Young) have located a valuable bed of pearls. A secondary plotline involves heroine Jerry Gale (Polly Ann Young, sister of Loretta), who is innocently involved in a murder. One of the more important roles is essayed by oriental actor Shia Jung, who earned the film's best reviews. Also featured are such silent-film veterans as Monte Blue, Jimmy Aubrey and Reed Howes, all of them hampered by shoddy cinematography.
