The title is a pun, "Second" referring not to lineage but a boxer's corner man (or woman in this case).

Complications arise when mobster Ike Arnold (Brophy), impressed by Cecil's punching, declares himself a partner, putting additional pressure on him to win.

Further muddying the waters is Ike's girl friend Gloria (Kelton), who's set her sights on Cecil, much to Molly's dismay.

Note: The gag of Cecil becoming enraged when he hears The Irish Washerwoman was recycled from The Three Stooges' short Punch Drunks, though in that case the song was Pop Goes the Weasel.

Many of Roach's contract players appear in uncredited bits, including Carl "Alfalfa" Switzer, Max Davidson, Charlie Hall, Harry Bernard and James C. Morton.
