The world outside the forest has been  ravaged by a deadly pandemic. The forest is all what eight-year-old Marko has known and the only person he knows is his paranoid, protective Father.
His most precious possession is his Picture Book where he believes he can find the answers to everything.
His life suddenly changes when he discovers an innocent gentle boy with Down Syndrome named Miko living on the edge of the forest. Things turn for the worse when the boys are left alone to fend for themselves against the hordes of the Infected.
Marko has no clear idea of what it means to have a mother, but the boys must go on a journey to find her. Outside the safety of the forest, Marko is faced with a shattered world shrouded in silence and full of danger and death.
