Young Irish boxer James Carabine arrives in New York from Ireland, his way having been paid by Peggy Nolan, a girl from his hometown who's sweet on him. Unfortunately, James falls for the trampy Marcolina, who hooks up with him when her boxer husband loses a fight due to the shady doings of friends of fighter Blanco Johnson. Peggy sets out to rescue him from the bad crowd he's hanging with and get him back into prime boxing form.
