In 1960’s Patagonia, a German doctor and an Argentinian family’s paths intersect. A guest in Eva (Natalia Oreiro) and Enzo’s (Diego Peretti) hotel, the stranger quickly becomes fascinated by Lilith (Florencia Bado), the couple’s little girl. Aged 12, she looks more like a 9 year old child, which makes the perfection obsessed doctor take it upon himself to help the girl mature at all costs. His charisma, and also his money-upfront politic, ease her parents’ acceptance of him. In the end, they realize Lilith was the subject of a genetic experiment, and the German doctor was no other than one of the most ruthless criminals in history.
