Based upon a description in a film publication, Myles Calthrope (Warwick) is an English soldier of fortune who drifts into the diamond mining fields of South Africa and finds employment with some diamond smugglers who masquerade as feather merchants. When he comes to suspect their true business, Myles is dismissed. He then goes to Cape Town where he falls in love with Joan Farrant (Wilson). She helps him to get a job with her brother, who is also secretly a smuggler. The police arrest Myles in an illicit enterprise of which he has no knowledge, and he goes to prison for three years. Eventually the real criminals are arrested, and Myles finds happiness with Joan.
