The story revolves around the attempts of William Brown and the other Outlaws to get their older brothers married, in order to appropriate wedding presents that they plan to exchange for things of their own desire.

After a series of unlikely adventures, the boys serendipitously foil a gang of fur coat smugglers, and receive a reward from the police.

Meanwhile, William is in the old barn with Henry and Douglas, in a make-believe game of 'The Knights of the Round Table', when Ginger arrives on a fabulous bicycle.
