In the early 1980s in Spain, Lola, a pregnant woman, marries Adolfo, the man who presumably got her pregnant. During their wedding, Lola suffers a
miscarriage and is told she cannot have children again, plunging her into depression. Adolfo talks Lola into
adopting children from the convent
orphanage nearby, and the two end up adopting Tin and Tina, twins with albinism of an older age than the couple originally planned to adopt. The twins share a gift for music and particularly strong religious beliefs that somewhat unnerve Lola. Although Lola and Adolfo are not religious, they pretend to be to make the twins happy. However, soon enough, the twins' odd religious beliefs begin to disturb Lola as they play disturbing biblical games that are practically lethal, and after Lola's dog bites her they kill it to 'cleanse its soul' without realizing it won't come back to life afterward. When the twins receive their
first communion, a classmate of theirs who bullied them
falls into a coma, and Lola suspects that the twins were behind it. Lola eventually learns that the boy is dead, but Adolfo refuses to believe her and does not seem too worried about the twins' behavior. Lola faints on
New Year's Eve and finds out that she
is pregnant, much to her shock and horror. The twins become overexcited about having a little sibling, and Lola grows more distant from them. After Tin and Tina tie Lola up and attempt to inject her with a potentially poison-filled syringe to 'feed the baby', Lola raises a knife to defend herself, much to the shock of Adolfo; her water breaks at that time, and after Lola gives birth the twins share enthusiastically that they want the baby to
be baptized. When Lola refuses, the children nearly drown the baby by trying to baptize him themselves. Lola and Adolfo become enraged, leading to Adolfo burning their
Bible and sending them back to the convent. Lola and Adolfo's relationship gradually starts to fall apart after Tin and Tina are sent back to the convent. Soon, Lola begins to contemplate a divorce. One night, as the couple are conversing, a
house fire ensues due to a strike of
lightning, leading to the death of Adolfo. In the chaos, Lola loses track of the baby. Suspecting the children are involved, Lola attempts to speak to God by nearly killing herself, then searches for and finds her baby, after which she runs from the burning house. Lola wakes up in a hospital and is visited by the head of the convent from where she adopted Tin and Tina. The head tells her that her husband passed away and that he was
struck by lightning. She informs Lola that she and her baby survived, which was a
miracle. Lola enquires about the children's whereabouts during that night and learns they were at the convent all night supposedly. The head assures her that the children have always been innocent and Lola believes her. The film ends with Lola at her husband's funeral, having adopted Tin and Tina again. == Cast ==
