The latest series of Spooks continues on BBC One and BBC Three this week with the transmission of the fourth and fifth episodes.
Episode 4: BBC One 9.00-10.00pm, Monday 2 October
A World Trade Organisation conference is taking place which could signal a breakthrough for poverty in Africa, as the high-octane spy drama continues.
The team is brought in to get the American and French representatives to vote "e;yes"e;… by fair means or foul.
Ros and Zaf work undercover at the conference hotel, providing them both with an opportunity for some flirting.
The French minister is soon convinced to vote "e;yes"e;, with the American delegate proving a little trickier but not far behind. Job well done, it would appear.
News of an assassination threat to an African leader at the conference forces the team into action. Acting on a tip-off that one of the catering staff might be in on the plot, the entire staff is replaced and Zaf leaves the hotel along with the departing team. But on his way out he realises that one of the waitresses is missing – is she the assassin?
The girl is found at the hotel banquet and whisked away with seconds to spare.
Under questioning, the girl reveals that the African leader is about to commit mass genocide on his own people.
The team checks out her claims, which appear to be true – so do they follow instructions to detain the assassin or take the law into their own hands?
Episode 5:� BBC Three 10.30-11.30pm, Monday 2 October
Ruth is troubled as she witnesses a man committing suicide – was he trying to give her a coded message by handing her a marked £10 note?
Following a Joint Intelligence Committee meeting, Harry questions the report on a fire at Cotterdam Prison in which seven terror suspects were killed.
�He suspects a cover-up and tasks his team with finding out the truth.
Meanwhile, Ruth’s enquiries into the suicide lead her to a grocery shop where she exchanges the marked £10 note for a disc.
�However, as she leaves the shop she is followed all the way back to Thames House and, upon arrival, is arrested.
Oliver Mace explains that the man who committed suicide was a Special Branch officer who had evidence that Ruth was colluding with the Cotterdam terrorists, and that she killed him when he threatened to expose her.
The disc, which Ruth hopes will prove her innocence, turns out to be blank and CCTV footage of the suicide has been tampered with.
Meanwhile, the team realise Ruth has been set up and try to prove her innocence.
Adam discovers that the deaths were faked and that Mace is responsible.
Mace owns up to Harry and threatens him – if he won’t support the ongoing cover-up of the torture of suspected terrorists, he’ll take Ruth down.
