Unknown to everyone but his shady Middle Eastern bosses, watchmaker Hawkins is actually a professional hired assassin with a predilection for killing his targets with bombs. After disposing of a dictator and millionaire, Hawkins is assigned to kill a politician who is heading to a remote hotel, The Green Man, for a secret tryst with his secretary. There, however, Hawkins' plot is discovered by vacuum salesman William Blake, who determines to stop him.
Unfortunately the movie The Green Man is not yet available on Disney Plus.
