Ep 5. I Spy Apocalypse

Tom Quinn, Zoe Reynolds, and Danny Hunter are sent to a safe house in Bolton to track down a Serbian war criminal by the name of Milos Pavelic. Milos is hiding in the UK under an assumed identity, and there is no information about his current whereabouts. The team is tasked with finding him before he can plan and execute a large-scale terrorist attack in London.

In order to obtain information, the team enlists the help of Kasia Baran, a woman who was rescued from a human trafficking ring and is now seeking asylum in the UK. Kasia has information on Pavelic's whereabouts, but she is hesitant to share it as she fears for her own safety.

As Kasia starts to open up to the team, it becomes clear that her past experiences have left her traumatized and distrustful of law enforcement. Tom tries to gain her trust by sharing his own experiences in MI-5, but Danny is frustrated with the slow progress and feels that they need to use more forceful methods to extract information from Kasia.

Meanwhile, Harry Pearce is dealing with his own crisis as a controversial journalist named Toby Mundy threatens to expose MI-5's unethical practices to the public. Harry tries to keep the situation under control, but Toby refuses to back down and threatens to publish a damaging article in the next day's newspaper.

As the team follows Kasia's lead and gets closer to Pavelic, they realize that the situation is much more dangerous than they initially thought. Pavelic has access to highly advanced technology that would allow him to launch a devastating attack on London, and the team must act quickly to prevent the worst from happening.

With time running out, the team must make difficult decisions and face the consequences of their actions. Will they be able to stop Pavelic and prevent a catastrophic terrorist attack? Or will they fail, and London will become a city in chaos?
