During an army training stint for the C.A.T.S.EYES team, Sir Jack Fenn tells Maggie that they are holding a top Czech spy, Kessler, for debriefing.
On investigating the other recruits, she discovers that a number of them do not 'check out', and Fenn suspects that the KGB want Kessler - dead or alive.
Events take on an unexpected turn when a kidnap and subsequent murder attempt on Kessler are foiled by the team, and Fenn also has something to hide.
