 In Faversham, Kent, Walter Crane (Kevin Fuller) receives the message "rain from heaven" in Russian from a numbers station. Upon hearing this, Crane unburies a cache. Section D, having heard "Tiresias wakes 3 pm tomorrow" the previous episode, work on what the message means. Lucas North (Richard Armitage) and Harry Pearce (Peter Firth) discover Tiresias is the Russian equivalent of Sugarhorse, but "bigger and better;" while Sugarhorse placed pro-western Russians to infiltrate its government, Tiresias does the opposite; recruit spies to infiltrate the British Government. Ros Myers (Hermione Norris) believes Connie James (Gemma Jones), a mole from the FSB, might know what Tiresias is planning. Ros and Lucas release Connie from custody by posing as masked Russian agents. Later, it is revealed that FSB officers have been assigned to assassinate her. FSB head Viktor Sarkisiian (Peter Sullivan) orders a kill squad to search every MI5 safehouse, provided by Connie, to kill her and the Section D team who are harbouring her.
