After mastering crop farming, cafeteria management, and overseas expeditions, KKPP Food heads to a dairy ranch in Jeju for its first technical training. Welcomed by lush fields and newborn calves, the team quickly discovers ranch life is anything but easy. From overwhelming encounters with cow manure to unexpected accidents, Lee Kwang Soo, Kim Woo Bin, and Doh Kyung Soo face a messy and hilarious initiation. Can they survive their toughest training yet?

The second day in the Jeju farm begins, and they start to work from early in the morning. They still have a lot to learn, but they have somehow become skilled at farm work, so they even offer ideas for more efficient work to their seniors. Meanwhile, KKPP’s new intern, dispatched from the head office, comes to join as a new member and starts working with them. But this intern seems too shy to be close to.

Their yutnori with the ranch team for overtime exemption is not over, and they start the second round of it. Which team will win the bet? Meanwhile, their second day doesn’t seem to be over because they have to go on a night patrol of the ranch and play the game for their shower order. And the morning of the third day comes, and they do the same task as the second day, but they feel quite used to it, reducing their working time.

As it’s the last day on the dairy farm, the KKPP trainees prepare the farewell party under the leadership of the intern, Sang Hoon. Sang Hoon introduces himself as a skillful chef, but he loses his confidence as he starts cooking because of his poor leadership and relies on Kyung Soo’s opinion. After resolving the obstacles, they succeed in preparing for the party and make the day memorable with their seniors. However, another mission is waiting for them.

Love doesn't always go according to plan as Kyung Soo and Morris enjoy a calm bonding session, while Kwang Soo and John Snow charge headfirst into chaos during their horseback training. On the second day, a suspicious visitor sneaks into the ranch to pick bracken despite repeated warnings from the owner, leaving the trainees stunned.
