Alone in the paddocks of his grass hotel, a man tends to his beloved horses, Socks and Boy. The voice of his mother -- accusatory, fragmenting from dementia -- haunts his every move, an excoriating reminder of his failures in the world of people. "The Grass Hotel" is a story of damage and repair, of familial obligation and the resentments it can cause. It is also about the profound comfort that a connection with animals can offer.
