Children of Earth: Day Four

Jack is forced to confess how he helped broker a deal in 1965 when the 456 aliens offered an antidote against a deadly universal flu virus in exchange for twelve children who would 'live forever.' Clem and the team watch via Lois's laptop as the aliens tell Frobisher they will 'wipe out the human species' if their request is not met, and a camera reveals the apparently zombic Scots victims, said by the aliens to be unharmed. Frobisher rejects Jack's offer of help in return for Alice and her son's release. He attends a Cabinet meeting which agrees that the Cabinet's children will be spared and that lower-class kids should be sacrificed instead.This is recorded by Lois and sent to safety with Rhys,giving Ianto and Jack leverage to talk to the aliens but the latter's' response is to unleash a virus which kills dozens, including Clem and,seemingly,Ianto. The government feels forced to capitulate.
