Unreported World travels to Lebanon where an estimated 1.5 million Syrian refugees have fled the war. Reporter Shaunagh Connaire and director Andrew Carter reveal that, despite offers of assistance from the international community, some of those most in need - refugee children with serious medical conditions - are suffering and dying while they wait for help. The UK, other European countries and the US have promised to help the most vulnerable children and resettle them. However, Unreported World discovers that there are limits - on medical grounds - as to who is being accepted on some of these schemes, resulting in some of the sickest children and their families being left stranded.
