Joseph (Peter Mullan) is an unemployed widower with a drinking problem, a man crippled by his own volatile temperament and furious anger. Hannah (Olivia Colman) is a Christian worker at a charity shop, a respectable woman who seems wholesome and happy. When circumstance brings the pair together, Hannah appears as Joseph’s guardian angel, tempering his fury and offering him warmth, kindness and acceptance. (Paddy Considine)
