In the first episode, hosts introduce the 10 contestants and explain the rules. As the game begins, a wild animal is unleashed and contestants are challenged to sell condiments and grilling pans for a million baht. Who will survive the first episode?
In episode two, a legend is eliminated. 9 contestants remain, but any attempts to induce laughter only end in failure. But not to worry, the hosts have plenty of ideas up their sleeves.
This third episode introduces us to Phuak's new band, the Phuak Five, while Pexky brings her pet alligator to meet the other terrified contestants. However, it is Pingpong's surprise that nearly breaks several contestants. The hosts are stricter than contestants anticipate, prompting one of them to be punished and another rule breaker to be given a card.
In episode four, Pexky's pet alligator comes back to bite a contestant, just as a chaotic wedding brings unexpected laughter. Dr. Tum orders a detox for one very constipated contestant, and a special show challenges contestants not to joke, revealing a foul in the next episode.
In the fifth episode, the remaining contestants almost hurt themselves by trying not to laugh, but several are eliminated anyway. Will Tum's tactic to not laugh be able to withstand Zani's Granny act? The episode ends with suspense, hinting at an unexpected red card in the last episode.
In this final episode, Kyutae has to deal with the repercussions of a gassy encounter with Ticha. Special guests and the no-laughing rule push the contestants to the brink. Tonhorm's flute and Pexky's pageant conclude the show, resulting in a historic Last One Laughing win.
