The Little Irish Girl is Dot Walker (Dolores Costello), the pretty come-on for a tawdry gambling house. Dot lures country boy Johnny (John Harron) into the den of iniquity, where he loses his life savings. Seemingly undaunted, Johnny invites the crooked gamblers to his home, where they are introduced to his sweet, grey-haired old granny (Gertrude Claire) -- who pulls out a deck of cards and beats the gamblers at their own crooked game! Reformed by the experience, Dot falls in love with Johnny, and he with her. Dolores Costello isn't too convincing as a worldly type, but she's just fine in the final redemption scenes.
