John is still reeling after his discovery that a proxy attack is possibly being planned on UK soil to target a prominent Iranian dissident, but a visit to an informant's widow throws up contradictory evidence. John becomes convinced that there is a cover-up that permeates to the highest level. Meanwhile, John's refusal to accept voluntary redundancy means his relationship with Claire is on thin ice, and a visit from his in-laws only stokes tensions.
