Flies

Three lives intertwine in a massive apartment block in Mexico.

Olga lives a strict, closely regulated life, with no friends or close relationships, in an enormous apartment complex. When financial circumstances force her to rent out a room, a man moves in—and secretly brings his nine-year-old son with him. To her own great surprise, Olga begins to form an unexpected bond with the boy. Little by little, cracks appear in her carefully controlled life, and, against her will, the three lives begin to intertwine.
