    Summary

    Martha Jones has been compromised.

    Captured and cloned by the Sontarans inside the ATMOS factory, her replacement embarks on a one-woman mission behind enemy lines, covertly sabotaging UNIT from the inside. As the world slowly chokes to death on clouds of poisonous gas and UNIT threatens to launch a nuclear counter-attack, the Doctor scrambles to unmask the spy before hostilities escalate into all-out war.

    In the case of the treacherous Dr. Jones, however, the lines between memory and identity are beginning to blur... Whose side is she really on?
