In a seething Mexican-American bordertown, narcotics agent Miguel Vargas (Charlton Heston) clashes with detective Hank Quinlan (Orson Welles) – a local hero despite his dubious intuitions and bloated bigotry – as each investigates a potentially scandalous killing. Is the Grandi crime clan involved? What of Susan Vargas (Janet Leigh), keen to continue her honeymoon?

A Touch of Evil is out in cinemas on Friday.
