Lily (Eubha Akilade) confronts Eve and Will with evidence that Eve hacked into a nuclear reactor, but Will doesn’t believe it. Meanwhile Lily’s brother Abe (Elijah Ayite) wants to get Eve to do his after-school job delivering leaflets. But when Eve reads about the environmental damage caused by humans, her mysterious ‘Protocol Zero’ is activated and she starts to behave peculiarly. She cuts off the electricity to the house and then the local hospital, before giving Lily a massive electric shock. Will and Lily realise that Eve’s creator Mary Douglas (Jane Asher) is sending her secret upgrades. But can Eve fight off ‘Protocol Zero’?
