The Fugitive (1964)

Among the Brighton gangs, the Mods and Rockers, a teenager is victimised by a member of his own group, who then steals his girlfriend. He can take no more, and knives his rival in a fight. But his troubles are just beginning. His girlfriend is not coming back. The police are after him, as are the other members of the gang. Everywhere he is a fugitive. He suffers a breakdown, and fantasises that the doctors in the hospital are killing his injured rival, and that he will be blamed. He steals a bottle of serum that a doctor had used for an injection, hoping to convince his former friends that he is innocent, but it is just an empty bottle which will convince no-one. He finds himself cornered in a dark lane where there is no way out.
