In this comedy adventure, Marmaduke Clarke (Wesley Barry) is the spoiled son of a millionaire who is bored at home. When the house is robbed by crooks, Marmaduke helps their cause by assisting them. The boy runs off to be with gang-member Dumbbell (Niles Welch), a man he befriended during the burglary, but the crooks have other ideas, and they hold the boy for ransom and plan to kill him if the family does not come up with the money. Dumbbell helps Marmaduke escape when he learns the boy may be marked for death. The two find work on a farm where Dumbbell falls for Mary (Ruth Renick), the orphan girl taken in by the owners. The man is accused of kidnapping until he reveals he is really a secret service agent. The wayward son is soon reunited with his parents.
