The slow mental and emotional disintegration of the mother of an autistic child is the main theme of this evocative psychological drama by J.A. Salgot. Since incest and murder are also involved, this is not exactly a film for all audiences. Clara (Victoria Abril) is graphically shown giving birth and subsequently followed as she tries to cope with the ever-more obvious autism of her new son. She leads a normal life as a keypunch operator, but her son's affliction takes its toll. She experiments with illegal drugs, eventually loses her job, and slowly recedes into a shell that is almost as impenetrable as her son's. There seems to be no ordinary way out of her gradual decline, no solution to her problem that started long ago when she refused to give her son up to an institution.
