In the final part of this revealing series, we meet Andy and his 72-year-old dad Cookie, both surviving on Swansea's streets throughout the coldest winter weather for over a decade. Both are trapped by their alcoholism and both are constantly moved on by the local police. Andy is so desperate to escape the streets he turns to the church to help him get into a rehab programme. Two Christmases ago we filmed Stevie on the streets, he was also struggling with addiction and was even thinking about breaking the law just to get a prison bed. Now a year later, we meet him again, his life has been transformed. We also follow the unique and desperate stories of those seeking emergency shelter when their lives are on the edge.
