STORYLINE

The Doctor and Jo take the TARDIS on a test flight. They arrive on a cargo ship, the SS Bernice, that appears to be crossing the Indian Ocean in 1926 but is in fact trapped inside a miniscope — a banned peepshow of miniaturized life-forms — on the planet Inter Minor.

They enter another section of the scope but find themselves confronted by ferocious Drashigs. The Doctor eventually breaks out of the scope and returns to full size. The device is owned by a pair of Lurman entertainers, Vorg and Shirna, who hope to make a quick profit from Inter Minor's hitherto reclusive natives.
