Yeissy, a former child soldier in Colombia, wants to become a doctor. But that's easier said than done. Society often has trouble accepting child soldiers because of their violent past. 

War Child, a Dutch organisation which tries to help children in war zones, wants the International Criminal Court in The Hague to help former child soldiers, who were often forced to commit war crimes. As Yeissy says, "we young people no longer want to be part of a war that isn't ours".
