His Supreme Moment on AllMovie

John Douglas, a down-on-his-luck engineer (Ronald Coleman), takes his sweetheart, Sara Deeping (Kathleen Myers), to a play starring Carla King (Blanche Sweet), and he falls in love with the actress. Douglas proposes to Carla but, wary of marriage, she hesitates. Instead she proposes that she accompany him to his South American mine, posing as his sister, and after a year they can assess their relationship. The vengeful Sara comes down, too, and does her best to cause trouble between the couple. She creates a big enough rift between them that they wind up separating. Back in New York, Carla accepts the marriage proposal of a millionaire who offers to back Douglas in his endeavors. In the end she decides she must be with Douglas and they make plans to return to the mine, this time as husband and wife.
