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.

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.

Some of Swansea's most desperate homeless people face freezing conditions, urgently trying to find somewhere to live. Susan fell out with her family and has no choice but to sofa surf with friends. But she gets turfed out onto the streets and has nowhere else to go. Scott, from Llanelli, was evicted from a homeless hostel and is now sleeping rough. This time he's sleeping in an abandoned car. He's close to freezing to death whilst his mates have a bed for the night at a nearby church shelter. Paul, the one and only happy long-term Swansea homeless person, originally filmed for last year's series, continues sleeping on the streets, but he's back on the road and we now discover him living on Canterbury's streets.
