“Stop this war. Or you will die.” With these words and the destruction of Turin, the alien Mi-go launch a bid for domination of the Earth in 1940. In response, Berlin and London each send small teams of highly-trained men into the Andes to investigate the suspected site of the aliens' deadly weapon and neutralise it. Although the German team is captured by the Mi-go, the British soldiers are successful, and call in a bombing raid which destroys the alien base.
- Sandy, the narrator and British team member.
- Captain Dave Collins, leader of the British expedition.
- The name of the mountain on which the Mi-go base is located, the Trollenburg, is possibly a nod to the 1958 sci-fi horror B-movie The Trollenburg Terror, which features a Lovecraftian creature on a mountain of the same name.
