Trevor Newell is a hero, though the world around him in the English Midlands of the 1970s sees only a colourless teller behind the counter of the local bank. In the privacy of his own room in his mother's house, Trevor lives in an escapist world of violent movies, but when fantasy meets reality and brutal robbers come to his bank, his character is tested as he finds himself drawn into a world of harsh realities. Will the Celluloid Kid grow up and does growing up always mean being physically and mentally tough or is there also room for compassion?
