After a man named Charlie Collins curses at the Joker on the road for offensive driving, the Clown Prince of Crime corners him and intimidates him into doing him a “small favor”. Two years pass, and the Joker finally decides how to use Charlie: to sneak a bomb into the Peregrinator’s Club, where Commissioner Gordon is to give a speech at an award ceremony. Charlie, who merely has to open the door, is skeptical at first, but for the sake of his family, he reluctantly decides to obey.
