Devil Within on AllMovie

When the brutal Captain Briggs (a miscast Dustin Farnum) destroys a Malay idol, a native witch (Evelyn Selbie) puts a curse on him. From there on in, death follows him. He marries, but his wife dies when their son is born. The son reaches adulthood and weds, but the couple catch a fever and die, leaving Briggs with an orphaned grandson. The boy, Hal (Bernard J. Durning, also the film's director), grows up to be as violent and mean-tempered as his grandfather. He gets into a brawl and is stabbed by a poison dagger. Briggs, who had once had his own encounter with a poison dagger, has both the poison and the antidote -- unfortunately, he doesn't recall which is which. But he risks his life by tasting one of the powders. It turns out to be the antidote, and he gives it to Hal, who recovers.
