M

Martin W. Harrow (David Wayne) is a compulsive child-murderer who is tracked down and then placed on trial by the criminal underworld in Los Angeles. Syndicate chieftain Marshall (Martin Gabel) organizes his fellow crooks in order to bring "M" to justice, thereby keeping the police off their own backs. Found guilty by his "peers" and sentenced to death, "M" makes an impassioned plea for his life, explaining that he is unable to stop himself from committing his unspeakable crimes.
