At an expensive English boarding school for boys, Roddy Berwick (Ivor Novello) is School Captain and star rugby player. He and his best friend Tim Wakeley (Robin Irvine) start seeing a waitress Mabel (Annette Benson). Out of pique, she tells the headmaster that she is pregnant and that Roddy is the father. In fact it was Tim, who cannot afford to be expelled because he needs to win a scholarship to attend Oxford University. Promising Tim that he will never reveal the truth, Roddy accepts expulsion.
