A double bill of Costa-Gavras directed films starring Yves Montand. In 'Z', Montand plays the assassinated leader of the opposition pacifist party in a totalitarian regime. The investigating magistrate pursues the truth at great risk to himself. In 'State of Siege', Montand plays an undercover CIA agent who is being held hostage by South American guerillas. It soon transpires that the ruling dictatorship is only upheld with secret support from the US Government.
