Nicola is a 6-year-old boy who lives with his family in an old apartment divided in two by a long corridor. His parents' relationship is slowly falling apart, as money is running low and love is fading. To escape the violence, Nicola hides himself in the fantasy world of his toy soldiers. But as the tension increases day after day, the young boy begins to see the corridor slowly turning into a war trench and getting to the front door is no longer a matter of going to school, but the only way to survive.
