The death of his wife, and his experiences in the Trenches of WW I, have left photographer Charles Castle a spiritual sceptic. Then a single photograph brings him face to face with the possibility of worlds beyond our own… Inspired by the true story of Arthur Conan Doyle and the Cottingley Fairy Photographs, and with a stand-out performance from Sir Ben Kingsley as the girls' vicar father, this dark fantasy of ideas explores the limitations of rationalism and the human need for Belief.
