Utopia (UK Series)

In 1974, young scientific genius Philip Carvel meets an idealistic security services agent, Milner, at a secret forum of political, industrial, financial and academic leaders. Milner is in charge of a powerful shadowy organisation known only as The Network. Together they hatch a radical plan they believe will save the human race from the horrific ramifications of over-population.
Five years later, in the 1979 winter of discontent Carvel is tormented by his love for his daughter Jessica and his guilt over what he has done to his son, and is beginning to lose his mind. He has made an adjustment to Janus and is refusing to release it to Milner. But a determined Milner refuses to let either political events or Carvel's impending breakdown get in the way of their goal.

In the present day, Jessica has been held captive by Milner who has tortured her in a desperate attempt to find out just what adjustment Carvel made to Janus. Ian and Grant are desperately searching for Becky. The Network is planning V Day - a strategy to vaccinate the whole world from Russian flu and Geoff is being forced to sell the idea to the nation.
When Lee turns up at Arby's new house, no one is more surprised to discover he's alive. But can he force Arby back to his old ways? Ian finally finds Becky, but she's with Donaldson and a mysterious hostage named Anton. When they're suddenly targeted, a lone gunman is close by to save them - but they are shocked to discover who their rescuer is.

The gang are on the run and find a precocious young hacker, who uncovers the key to The Network's new plan: a real global outbreak of weaponised Russian flu that will prompt the entire world to take up their vaccine on V Day.

A shocked Dugdale reluctantly agrees to harbour Jessica, but who should be scared of who? When Dugdale visits Jen and Alice in a secret prison it's clear he will do whatever The Network asks in order to keep his family alive. Jessica is searching for Ian, as is Milner who is convinced he will lead her to Carvel.

In the penultimate episode, following the revelation that her father is alive, Jessica sets off to find him, with hostage Milner in tow. Meanwhile, Wilson and Leah analyse their information and discover the far darker and more terrifying secret it holds.

In the final episode the race is on to find out who is going to release the flu. The gang track down Dobri Gorski to a police cell, where he tells them the names of the three people he trained to release the flu. A process of elimination leaves them with Terrence, but they still have to find him. Wilson's new ruthlessness is unnerving - can he be trusted? And what will happen when Becky runs out of Thoraxin?
