Antique collectors Wilbur Talbot and John Wilton are friends until Wilbur secures a Chinese vase that John had long coveted. The enmity that then grows up between them is so fierce that when their children, Roger and Muriel, marry, the young people are disinherited. On a farm near the Talbot home live The Hopper, a reformed crook, his wife Mary, and their friend Humpy. One afternoon, The Hopper, believing that a detective is after him, appropriates Roger's car for his escape, but when he discovers little Roger, Jr. on the rear seat, he returns the child. There he encounters Muriel, who, hoping to end the feud, asks him to steal the Ming vase from Wilbur and an equally valuable piece from John. The two old men then accuse each other of robbery and kidnapping until The Hopper enters with the china and the child. Watching their grandson romp about the room with the antiques clutched precariously in his little hands, they agree to shake hands and reunite the two families.

"The Hopper" is a reformed house-breaker who marries and settles down to chicken farming. He consents to return to his old profession and "turn a trick" to oblige a young woman who has married against her father's wishes. The old gentleman and her husband's father are collectors of antiques, and have quarreled over the possession of an ancient Chinese vase. "The Hopper" steals it as requested, and his act is the means of patching up the quarrel between the two families.—Moving Picture World synopsis

Old friendship was not proof against the collector's envy, and when Wilbur Talbot digs up a most unique Chinese vase it costs him Wilton's friendship. But their children marry, and are disinherited. Then Muriel has a great idea. Chance sends her a burglar, and she hires him to steal the vase and a saucer that her father highly values. The Hopper gets the saucer without trouble, but Wilton is before him at the Talbot home, and while the two collectors are fighting the Hopper calmly walks out with the vase. It results in the reunion of the two families, but it looks as though it might mean the police court for them all.—Moving Picture World synopsis
