Season 1 of Crossing the Ocean premiered on June 21, 2018.

Deunsip is a modern woman in a middle-class family. Her family consists of father, mother and younger brother, Duan. Her family is in a terrible situation because Duan is using drugs. It is the main reason for the family of Lamtarn, Deunsip’s boyfriend, to question their relationship. Lamtarn’s family is well-known in high society, so his mother doesn’t want him to pick a girl with a bad family background, like Deunsip. Yupra, Deunsip’s close friend, decides to take her on a trip to southern Thailand, in order to get away from the conflicts for a while.
