Un horrible secreto se oculta en el desván. (A horrific secret is hidden in the attic.)
When the single mother nurse Gloria has financial difficulties, her colleague and friend Dr. Ana Torres invites her to move with her six year-old daughter Vicky to her old big house where she runs a gynecologic clinic. In return, Gloria would assist Ana in her clinic in the afternoons. Sooner Gloria finds that Ana dedicates to abortion in her clinic, and also that she is lesbian and has a crush on her. When Ana gets pregnant of her lover Javier, Ana proposes an abortion, and after more than three months, the reluctant Gloria accepts her offer with tragic consequences.
