Synopsis by Janiss Garza
During the silent era, there was a lot of interest in spiritualism and clairvoyance. This independently made drama banks on the trend. As young children, Dorothy and Robbie Carlton are orphaned. But before she dies, their mother promises she will always be near to protect them. The children live in Galveston, and during the great tidal wave of 1900, they are separated. Robbie is adopted by Dr. Richard Stanton (H.A. Cross), a noted surgeon, while Dorothy, who has lost her memory, is renamed Blanche and is taken in by kindly Captain Smith (Grant Foreman) and his wife (Elizabeth Yach). The siblings grow up (to be played by Hermain France and Willard Burt) and eventually meet, each unaware of the other's identity. Twice Robert saves Blanche from danger because of an invisible presence urging him to look out for the girl. Eventually Robert becomes Stanton's partner and after he has saved Blanche from a fire, she drags out her convalescence because she wants to be near him. They fall in love and plan to marry. Captain Smith, who is at sea, finds out that they are brother and sister, but can't get word to them in time to stop the wedding. Robert, however, has a psychic warning that something is wrong. Before the marriage can be consummated, the siblings discover their true relationship and avoid disaster.
