The Rutan has important news regarding the war and the Sontarans, and upon hearing the news, attack the Tiger Moth and take it over. The Rutan hides itself among the crew and one by one the Sontarans and the human crew are murdered by the Rutan. The Sontarans plan to destroy all life on the Tiger Moth. Can Lisa find out who the Rutan is before the Sontarans destroy her ship and her life?...
