Madeinusa is a fourteen years old native girl of South America, who lives in a distant village in the Cordillera Blanca of Peru. This place is well known for being fervently religious. The whole village is allowed to do anything they wish from Holy Friday, at three o’clock in the afternoon, when Jesus Christ was crucified, until the following Resurrection Sunday. During the “holy” days, sins do not exist: God is dead and he cannot see them. Everything is accepted and allowed, without any repentance. Year by year, Madeinusa, her sister Chale and her father Don Cayo, one of the most important people in the village, keep to this tradition without questioning it in any way. Then, everything is changed by the arrival of Salvador, a young geologist from Lima, who will unwillingly transform the protagonist’s destiny.
