Callan Season 2 Episode 1 Red Knight, White Knight

The Section has a new Hunter, a rather naive ex Army man. Callan hasn't been working at the Section for a while, but has been dropping in at the firing range for pistol practice every now and then. The new Hunter decides that he wants to see Callan, and orders Meres to go and collect him.

After telling Callan that he is wanted full time back at the Section and threatening him into the bargain, Hunter tells Callan that a KGB agent called Bunin is defecting . Callan knows Bunin extremely well and is immediately suspicious.

Callan interviews Bunin at his hotel room. Bunin says that they are all pawns, and likens their business to a game of chess. Eventually Callan discovers that Bunin's real target is one of their top men, Truman, who is found executed by Bunin who has since gone into hiding. Hunter is to be the next target.

Hunter rather naively sets himself up as a target in order to lure Bunin into the open, and Callan and Meres spend the night protecting Hunter. It is not until the following morning that Bunin comes out into the open, and he is nearly successful in executing both Hunter and Meres. It is only Callan's heightened sense of danger which saves them all.
