Sylvia sets off on a sea voyage with her husband Leon and his 24-year-old son Daniel — and from the very first night, her dreams are haunted by someone other than her husband. A storm, an accidental closeness in the water, lost underwear on the shore — with every episode, shame and desire blur into one. She fights to stay faithful, but her body keeps betraying her, responding to Daniel instead of Leon. A story of forbidden attraction, a stolen bed, and the constant risk of being caught.
