Utopia

Young scientific genius Philip Carvel meets idealistic security services agent Milner and they hatch a plan to save the human race from the horrific ramifications of over-population.

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.

The gang is 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 that he will do whatever The Network asks in order to keep his family alive.

Following the revelation that her father is alive, Jessica sets off to find him, with hostage Milner in tow. Meanwhile, Arby has taken Anton and Grant to a remote place from his past.

After discovering the vaccine won't work, Ian and Becky join forces with Wilson and the Network to stop the sleeper agent from releasing the virus; Jessica stands watch over her injured brother.
