Igor--a 15-year-old apprentice mechanic--spends his off hours at the beck and call of his father. Igor's father, Roger, is a low-life involved with smuggling undocumented immigrants into Belgium, and acts as their slumlord, housing them in barely livable conditions, and paying them menial wages to work construction on his building (among other scams). When the building inspector pays a surprise visit and Amidou falls off a scaffold in his hurry to hide, things start to unravel, particularly when Igor makes a promise to the injured Amidou that ultimately exposes the different values of Igor and Roger, and of Amidou's wife, Assita.
The Promise
Roger uses his son Igor to ruthlessly traffic and exploit undocumented immigrants. When one of the immigrants is killed, Igor is guilt-ridden and wants to care for the dead man's family against his father's orders.
