A portrait of an invisible man and an authentic account of homelessness within contemporary Britain, Hec McAdam is at once a powerful character study and an insight into the lives of those on the margins. Hec has been living around the motorways with transient friends for years. After so long on the move, he hopes to have left his past far behind. We follow his annual pilgrimage, on the roads and in the cities, from Scotland to a shelter in London to be with his temporary Christmas family . But his clock is ticking and he is compelled to try to reconnect with his real family he last saw 15 years before.
