A Madrid waitress, Lucia, is mourning the loss of her boyfriend Lorenzo, who passed away mysteriously. Unable to come to terms with his death, she takes a trip to a Mediterranean island that he told her about long ago, thinking about the novels Lorenzo wrote and the way that his work moved her. In flashbacks Lucia remembers her passionate relationship with him, and tries to reconcile some unresolved feelings. She is also debating whether his death was a suicide or simply an accident. Shifting time frames and memories combine with Lorenzo's stories and blur the activity of the present. Meanwhile, Lucia befriends some people at the beach - Carlos, Elena and Belen - with whom she finds common ground and another layer of connection to Lorenzo.
