A couple who have been married for twenty years decide to take a sailing trip to reignite the passion, accompanied by a friend and his new girlfriend. During the voyage, a storm breaks out and the sailboat is adrift.

After twenty years of marriage, a teenage daughter and successful careers, Nacho and Lucía have not been alone for a long time. The routine killed any intimacy left. They look at each other and sometimes they don't recognize the other person they are seeing. He became addicted to his production company and she became addicted to her restaurant. The new anniversary confronts them with the issue of time: how are they going to live their next years? Why are they still together? Do they still want each other? If they met today as they are now, would they fall in love again? Spending a romantic vacation on a luxury sailboat seemed like a great idea to Nacho, and Lucía accepted. However, while on the mainland each one makes his life for himself, on a sailboat there is nowhere to escape, there are no truces. Fear wins over them and they invite Ramiro, Nacho's best friend, and his new girlfriend, the younger and free-spirited Cleo. The young couple who will seem to save them will also confront them with everything they lack. The first hours on board the boat promise an enthusiasm that will not be able to be sustained. As an announcement of an incoming disaster, the sailboat begins to have damage and a storm ends up breaking the boat. Lucía and Nacho are left alone and adrift. They look into each other's eyes: there is hate, love, resentment, desire... Faced with imminent death and stripped of everything, they must find a way to survive.—exe_malaga93
