Barbara Köster is suddenly alone: her baby daughter Leonie moved out when she was eighteen, as did her husband Walter years ago, who left the family for a younger woman. At 58, Barbara is left alone - alone in a house that is too big for her, alone in a job that doesn't fulfill her and alone with the stale feeling that she has missed out on something in life.

The story of hotel manager Michael Hagen, who finally wants to catch up on his long-promised honeymoon with his wife Rebecca. But Michael's boss has other plans: Michael is to take over the luxurious but increasingly run-down hotel "El Sol" in Mallorca and find out why the already few guests are increasingly leaving head over heels. To avoid disappointing his wife and losing his job, Michael keeps his assignment secret and flies to the Balearic island with Rebecca in the hope of making their dream vacation together possible after all.
