Louise Grayling escapes from a straight-laced aunt on a plea that she wants to visit her uncle, Captain Abe, on Cape Cod. Abe is henpecked by his housekeeper and rather looked down upon by the villagers who haunt his store. To give himself a fictitious glory he invents a fictitious brother, Amzon, who is a composite of all the pirates from Blackbeard to the food profiteers. Louise penetrates the deception and induced Abe to go away and come back as the fictitious brother.
