Nina and Ben have been together for many years. They have a three-year-old daughter. Their first vacation without their child leads them to the south: to Formentera. Caressed by the sun and the warm Mediterranean winds they enjoy their freedom from the necessities of everyday life. Finally they have some time on their own.
But during a wild beach party the paradise turns into hell: Ben is firting with the young and beautiful Mara and at the end of the night Mara und Nina dive into the dark sea. Nina is drifted away and only just manages to get back on land on a different island.
Mara, however, has gone missing... Nina and Ben are caught in a deep crisis, questioning everything they once believed in. The sunny island turns into a darkroom, rendering visible what has been concealed: doubts concerning the plans they had for their lives and a quiet grief over a reality that may only be accepted.
