Leo Castaneda has been driving the metro line 6 in Brussels for years. One night he notices a
young man standing too close to the edge of the platform. The stranger jumps in front of the
train - at the last second Leo recognizes the face of his son Hugo whom he hasn't seen for two
years.On a dangerous search for the reasons for his son's tragic death Leo delves deep into
the criminal underworld of Brussels. The police are of no help to him - they consider him
suspicious themselves. Because for a normal citizen he is a bit too good with weapons. So Leo
must rely on his own skills to find those responsible for his son Hugo's death.
