In the film, "Rover," must rescue a baby who has been stolen from her maid by a gypsy. He trails them to an attic hideout, then races home to bring the infant's father (Hepworth) back to save her. Most of the footage is devoted to the dog's brave journey, a brand new concept in film at the time. The public loved it and Rescued by Rover became so popular it had to be remade twice because the original negative degraded to badly.
Hepworth cast his own wife, who also wrote Rescued by Rover, and baby daughter for the film, as well as the family dog, Blair.
