Retrieving the Annihilator, Perkins, Hoffman, Ralph and Polcor return to Arrow, to be captured by the Middle Eye, an alien race appearing as sentient, eye-like beings. Polcor's accusations against the humans are easily countered by Perkins; still, the Middle Eye decides to keep the humans as prisoners to learn the location of Earth from them. Polcor, on the other hand, is punished for his deceit by being forced to watch his home planet getting destroyed by the Middle Eye. In revenge, Polcor frees the humans and enables their escape from the Eye's ship before they can be interrogated, and with the help of Professor Common they return safely to Earth.
