One Man in a Million (1921)

Lupino Delchini, a waiter in a little restaurant, is discharged for giving food to a penniless beggar, and Detective Hartley rewards the Italian by getting him an appointment as pound master. Flora is attracted to Lupino by his kindness, but when he adopts a small Belgian boy, he falls in love with Madame Maureveau, whom he believes to be the boy's mother. Madame Maureveau accepts his marriage offer only to avoid being deported; she's actually in love with Hartley, who traces her real son to another family. Renouncing his engagement, Delchini finds happiness with the boy and Flora.
