When Alistair’s wife, Alison, commits adultery on their wedding day and shortly afterwards he is savaged by a ferocious dog, Alistair hits rock bottom, unable to cope with even the most undemanding of life’s tasks. From the depths of despair, he is galvanized into action and in true anti-hero style sets out to take revenge on those who have wronged him. Through taking this action, he is re-born.
