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.

As Danny Rowland, a tramp, and his partner Dominie, an ex-minister, trudge wearily past the Winnicrest mansion in Tennessee, an old servant called Uncle Alex rushes up to Danny and welcomes him home as his long-lost employer, Richard Castleman. Amused, Danny assumes the role, and he and Dominie are clothed, fed, and generally treated like royalty.
