After running into something with her car, Vero experiences a particular psychological state. She realizes she might have killed someone.

Lala, a teenager from the most exclusive suburban neighborhood in Argentina is in love with the Guayi, the 20-year-old Payaguayan maid working at her place. They dream of living together in Paraguay, at the shores of lake Ypoá. Robbing every purse and wallet in the house to fulfill their dream, hiding the money in a shoe box. But when the box is full, it bursts, fueled by desire, jealousy and rage. This is the starting point that spurs the escape through the highway that connects the North of Buenos Aires with Paraguay. While Lala waits to be reunited with her lover in Ypoá by reconstructing her past (the mystery surrounding her pregnancy and the legend of a fish child who guides the drowned to the bottom of the lake), the Guayi is detained in a minors institute in the outskirts of Buenos Aires. She turns out to be hiding a crime from long ago.

This is the dramatic story of a intersexed 15-year-old. She lives with her parents, who have to cope with the challenges of her medical condition.
