When Mark gets a date with a woman named Debbie Pledger, Hardcastle has to find a new player for poker night. To the judge's regret, Judge Mattie Groves, Lieutenant Frank Harper, and bailiff Charlie Masaryk, the other poker players, arrange to have Assistant District Attorney Freddie "Bummer" Bumgarner, a man Hardcastle despises, join them for the game. Meanwhile, a nearby liquor store is robbed. Needing a place to hide, robbers Tommy Kitchens, Crazy Horse and Joey Britton flee to Hardcastle's estate. Entering the judge's house, the robbers quickly take the poker players hostage. The situation worsens when they discover Frank is a cop and shoot him. Arriving at the main house to get some wine, Mark learns about the hostage situation. With some help from Frank, who was left in one of the bedrooms, Mark prepares a trap for the robbers. Thanks to an uncharacteristic heroic act on Freddie's part, Mark is able to successfully implement his plan and capture Tommy and his men.
