The soldiers line up for payday, and then get ready to enjoy the weekend, getting dressed in the barracks. Maggio cheers Prewitt up (Prewitt's moody because of "The Treatment") and drags him into town.
A dude named Maylon Stark tells Warden that Karen Holmes used to have affairs with lots of guys at Fort Bliss—and that he was one of them.
Warden meets Karen on a park bench, and they argue: Karen thinks he probably thinks she's a tramp, but he denies it.
He says he's taking chances on getting court-martialed by dating her. They make up—both have bathing suits on under their clothes and they decide to go to the beach.
Prewitt and Maggio walk around downtown Honolulu drunk, and go to a place called The New Congress Club.
The woman who runs it, Mrs. Kipfer, chides them for their heavy drinking but lets them in. Sgt. "Fatso" Judson is loudly playing the piano.
One of the "hostesses" tries to show Prewitt around, but he notices another hostess and decides to go talk to her.
Her name's Lorene, as Prewitt learns when they start to chat and hit it off.
Maggio causes a disruption, however, telling Judson—who runs the stockade—to stop playing the piano. Judson calls him a "Wop," which escalates things. But Prewitt and another soldier break up the fight.
Lorene's moved on to talking to someone else, but Prewitt comes back and jealously sulks, listening to the conversation. Prewitt argues with the soldier, driving him and Lorene away.
