People who look like yakuza are in Gintoki's house and seem to threaten him, over some matter. At the same time people from the same group are at Hasegawa's house about doing the same thing. After one of them makes a call, somehow Gin, Kagura, Shinpachi and Hasegawa end up in a boat in the middle of the ocean, fishing for some tuna. And another person is on the boat, a man with a turtle shell on his back.
Both Hasegawa and Gintoki are being questioned by debt collectors who decide they should go tuna fishing to pay it off.
After the episode title the Yorozuya and Hasegawa are fishing. Kagura pulls up a big fish, Shinpachi pulls up a small fish, Kagura laughs at him, Hasegawa pulls up a blowup doll and is punched by the captain(?) who is wearing a turtle shell after he becomes depressed. They continue fishing in order to become men of the sea.
After a quite well paid job, waiting for the elevator, the three Yorozuya are deciding to go out and eat Korean BBQ.But when they get on the elevator together with an old man, they notice after a while that they're stuck. And after they run out of plans to get out, Shinpachi desperately tries to liven up the mood.
After the ad break the Yorozuya have just been paid and are planning to have Korean BBQ. They enter an elevator and a man manages to get in before they press the button. The elevator stops at the thirteenth/fourteenth floor. They try pressing a button but it doesn’t work. When Kagura is hitting the buttons, Gintoki points out the emergency button and Kagura breaks it. The man in the elevator points out that they’re the only people in the building since everyone has gone home and that he’s the security guard. They wait, Shinpachi is able to remain positive, he finds out the the man’s house has burnt down when he tried to cook Korean BBQ at home. He still tries to remain positive and starts dancing, clapping, and singing. He collapses after he starts kicking the man who had admitted his wife was a blowup doll. Gintoki and Kagura take up their bokuto and umbrella and smash a hole in the floor and start climbing down carrying Shinpachi. They leave the man behind, and the elevator door has been fixed.
