Maria is a girl in her early teens whose family lives in an upscale gated suburb. Maria's parents are going out of town for a week, and rather than leave her with relatives or hire a babysitter, Maria is put in charge of looking after her little sister Sofia, with housekeeper Esther serving as a nominal adult authority figure, though for the most part she lets Maria and the others do what they please. With only their parents bedroom off-limits, Maria and Sofia have the run of the house, and soon they and their friends Facundo, Quique, Rodrigo and Timmy are spending their days exploring the place. As the kids begin creating their own rules to run counter to the ones their absent parents set down, Esther brings a young relative, Fernando, to play with them, and the privileged kids begin to get a notion of the ways of the outside world.

It tells the story of four Jewish boys during a few summer days at the country club where their parents take them, on the outskirts of Buenos Aires, in 1993. Within the club, the four define themselves as outsiders, since they do not participate in the sports activities that are practiced there, and therefore do not fit into the logic that governs the place, being permanently bothered and mocked by the rest of the children of their age.
