At 36, Dom is a high sea fisherman who only comes back to land a few days a month. In spite of his long absences, he has custody of his two children. Dom does all he can to be a good father. He even dreams of having a business of his own : a small charter business he would run with his son. Mailys and Mattéo are grown-ups, but still, they are two teenagers who make their own experiences - one of which is going to force Dom to make a choice between a job on the open seas and a family life.
