Spooks is a BAFTA award-winning British television drama series produced by the independent production company Kudos for BBC One.

Series synopses

Main: List of Spooks episodes

Series 1

The series was a critical and popular success, averaging 7.5 million viewers over its six episodes, due to its combination of glossy high production values with fast-paced action/adventure and spy intrigue storylines.

The show quickly gained an unexpected edge with the violent killing of character Helen Flynn (Lisa Faulkner) in the second episode which drew the most number of complaints to the Broadcasting Standards Commission in 2002. During an undercover operation Helen and Tom were captured by race riot instigator Robert Osborne, played by Kevin McNally, who tortured Helen with a deep fryer in an attempt to make her superior Tom reveal classified information. He refused and she was killed. This provoked an angry reaction from many viewers who jammed BBC phone switchboards with complaints, despite the show airing after the 9 pm watershed. Nevertheless the death of Faulkner's character set the precedent that in Spooks anyone can die at any time.

Series 2

With the success of the first series, a second, longer series of ten episodes was commissioned and subsequently aired in 2003. This series saw the introduction of new main character Ruth Evershed in the second episode. It again drew praise, particularly for the fifth episode and the dramatic cliffhanger ending of the series finale. The series averaged 7.1 million viewers.

Series 3

A third series of again ten episodes was transmitted on BBC One in the autumn of 2004 and concluding 13 December. The first episode saw the introduction of Rupert Penry-Jones as Adam Carter, drafted in from MI6 to help investigate Tom's disappearance. He later took over Tom's position as Senior Case Officer as over the course of the series all three of the original leading trio (MacFadyen, Hawes, Oyelowo) left the programme, their departures staggered over the second, sixth, and tenth episodes respectively.

In episode six, Zoe is taken to court for misconduct during an operation and forced to leave MI5 and assume a new identity in Chile. She is replaced by Adam's wife Fiona (Olga Sosnovska).
