French comic actor Milton plays the titular "King of Bootblacks" in this slapstick romp. Fired for making a mess of a pair of expensive ladies' shoes (with the lady still in them), Milton takes a job as a bus driver. While tooling along zee boulevard, he spots the girl whose shoes he ruined sitting in a taxi -- whereupon he goes off his route, to the dismay of the passengers, in pursuit of the cab and its occupant. He continues chasing after the girl throughout the film, assuming such guises as a society dancer, a movie extra, and a "cardboard lover." Though he makes a pile of money at a gambling casino, by film's end he's returned to shining shoes, resigned to his lot in life.
