Society girl Rosalind Chalmers misses the last ferry to the Thousand Islands and is taken over in the decrepit motorboat of One-Cylinder Sam, who is really William Kellogg, heir to the Davidson millions trying to raise money for an expensive vase of his uncle’s that he broke. On the journey they break down and much to his surprise Rosalind, who’s hobby is engines, fixes theirs. Once landed the pair are off on a series of adventures with Rosalind mistakenly assuming “Sam” is a burglar until all is explained by which time they are in love.
