One of the words on Macquarrie's shoulder strap was "Plutonian" and the two scientists wonder if this stands for Pluto. The body of the alien suggests that it is not suitable for Pluto's harsh environment, but the planet may be a staging post for an alien invasion. Back at SUFOS Mortimer examines the alien weapon only for it to be stolen by Kaufman's assistant Jimmy Tcheng. Mortimer pursues Tcheng by car into the plains but they are caught in a storm and Tcheng is killed in an accident. It turns out that he is also an alien.
