Mila, a young wife, troubled by a strong marital conflict, decides to spend a time at the beach with two friends, Vânia and Cássia. Still wounded by her husband's betrayal, Mila sees in the figure of a fisherman, Galen, the possibility of a new and gratifying relationship of affection and love. However, she discovers that this fisherman, who in reality is a writer looking for events relevant to his book in preparation, gets involved with her two friends, in a purely physical relationship. This disappoints her. From there, Mila begins to have self-destructive urges, seeking death. Even through a moral degradation.
