In his play, Ted Willis deals with the so-called hooligan problem: Mandy Tullis, a young girl from London whose father has died, loves the member of a youth gang, the cynical-brutal Tago Martin, who has always narrowly escaped prison to escape. "Boss" of the gang is the failed student Alan, son of rich parents. One day at a meeting in the hangout, the young soldier Frank Morgan, an acquaintance of the family, appears to bring Mandy, whom he loves, out of the unpleasant environment and to bring her home. The gang reacts brutally, beating up Frank and throwing him into the street. However, the boys are observed and reported.
