"A father and son ride the rails in their powerful locomotive. Witnessing a crash between two other engines, they rescue the lone survivor, Berenice, and make her a part of their family. All is well until the father and son become rivals for the girl's affections and perform a series of dare-devil feats to win her heart. She runs off with a zeppelin pilot, and, after Keller mounts a brief kidnapping attempt, the despondent men are left to their bizarre fates."
