Ryu Jun-yeol embarks on a journey to Cuba. In a country he has never visited before, Ryu feels confused in doing many tasks alone, from hailing a taxi to changing his currency.

Jun-yeol promises to return to Abana soon and moves onto the next city. He finds a red, old-fashioned car on the way and decides to travel while driving it. However, the car suddenly goes missing.

It has been seven days since Jun-yeol arrived in Cuba. He hears the happy news that his colleague Lee Je-hoon is joining his journey. While Jun-yeol gets prepared to welcome him, Je-hoon is on a wild ride with a stubborn taxi driver.

Jun-yeol decides to become a one-day tour guide for Je-hoon. Je-hoon enjoys his first day in Cuba thanks to Jun-yeol's support. The two actors start to build mutual trust.

Two actors leave Abana and go over to Playa Giron, a city out of their comfort zone. The duo successfully arrives at the next destination thanks to Je-hoon, but Jun-yeol has a feeling that their trip will not proceed so smoothly.

The duo worries if they would fail to find a place to stay overnight. The next morning, they decide to put their worries away and dive into the turquoise-colored Caribbean sea.
