The Third Doctor and Sarah have landed on the Siccati colony of Cerulean. They meet sculptor Pug>llism and admire his creation. Suddenly the air raid alarms sound, and Pug insists they go to the Hippodrome, the only safe place. The Siccati head for the Hippodrome, but several are still left outside when the attack comes. From inside the Hippodrome, the Doctor, Sarah and Pug watch as the force field opens, and Pug’s creation fires at the attacking rocket from Vermill.
