Samhain is a young, angry and bewildered squatter living in an abandoned hotel in the North of England. One day he receives a message: his father - a man he never knew - was an undercover policeman infiltrating the Green movement in the 80s. What's more, he finds out that he too is now a father. Sam leaves for Europe, pursuing freedom and fleeing his responsibilities: but finds it impossible to escape. Guest is a story of disillusionment, protest, and eventually, redemption.
