A lost pet fox, a disconsolate boy, and a city (San Francisco): the boy, fatherless, raises and loves the orphaned fox, a gift from his beloved country uncle. The animal, lost in the city, occupies in turn Fisherman's Wharf, an amusement park ferris wheel, a Chinese herbalist's shop, and a Greek sculptor's studio. The eventual reunion of master and pet is followed by the happy announcement that Uncle Tripp is going to marry the boy's mother and move the whole menage to the country, The theme is old, the devices often tired and rarely involving, the urban variations only moderately inventive.
