A follow-up to the July 2016 documentary Exodus: Our Journey to Europe, finding out what happened to some of the one million migrants and refugees who came to Europe in 2015, and meeting others still making the journey. They include Dame, who arrived in the UK more than 17 months ago, and describes life as a refugee in London as like being 'a ghost in a prison'. Meanwhile, newlyweds Ali and Sharin from Afghanistan have spent the past month camping on the streets of Thessaloniki, waiting to be smuggled across the heavily guarded borders into Macedonia and Serbia - not quite the honeymoon they were expecting.
