Terrorism, kidnap, hijacking and espionage are the daily dangers faced by David Barber and Tom Duffy, chief operatives for Saracen Systems - a private security firm whose clients are governments, industry and individual contractors worldwide.

Their backgrounds and personalities are radically different: Barber, tall, dark and with typically English reserve, left the SAS when a mission went tragically wrong; the blond, rugged Duffy is a relaxed, ruthlessly charming American trained in the elite Delta Force. Their contradictory qualities make for a volatile friendship but a highly professional partnership. Under Saracen's founder and director, retired army officer Colonel Patrick Ansell, the agents take on high-risk tasks too sensitive or unpredictable for other agencies to handle.

Recalling the classic action series of the 1970s, this fast-paced, no-expense-spared series from Central features exotic locations and breathtaking action sequences (with input from legendary stunt co-ordinator Peter Brayham); the regular cast features Christian Burgess, Jimmy Clarke, Michael Byrne, Ingrid Lacey and John Bennett, with guest appearances from Lou Hirsch and Z-Cars legend Stratford Johns. Saracen also features theme music by celebrated composer Barrington Pheloung.

Available on DVD for the first time, this release contains all thirteen episodes, originally screened in 1989, as well as the pilot movie from 1988, The Zero Option - an account of Barber's failed SAS mission and his subsequent recruitment by Saracen Systems.
