Screen legend Michael Caine (The Wilby Conspiracy, The Holcroft Covenant, The Whistle Blower) is a British secret agent targeted for death by friend and foe alike in this riveting tale of mystery and suspense directed by the great Don Siegel (Dirty Harry, Charley Varrick, Madigan). This breathless story of international intrigue finds a determined Caine taking up the revenge trail when ruthless gunrunners kidnap his young son and demand a king?s ransom in uncut diamonds for the boy?s release. With each new lead Caine?s chilling quest becomes increasingly deadly as he begins to suspect that one of his colleagues is in league with the merciless abductors. Donald Pleasence (Halloween), Clive Revill (Avanti!), John Vernon (The Outlaw Josey Wales), Joss Ackland (White Mischief) and Catherine Schell (The Return of the Pink Panther) are among those involved in the spine-tingling, high voltage chase that ends at the infamous Black Windmill. One of the many highlights of The Black Windmill is the rousing score by composer extraordinaire Roy Budd (Get Carter, Kidnapped).
