A pet dog, the greatest treasure of his mistress, while out riding one day in his mistress' automobile, is attracted by the sight of a cat. He jumps from the auto to chase the feline. During the pursuit the collie is lost and tormented by two small boys, who tie a tin can to his tail and chase him. Later he is rescued by a ragged boy, whose home is any place where he can lay his head. Upon restoring the dog to his mistress the boy is rewarded by a good home.
