Space Security Agent Marc Cory crash lands on the planet Kembel. He's looking for the Daleks. Well, he found them. The Daleks have formed an alliance with some other baddies, and they're going to invade Earth. Cory manages to send a warning signal to Earth before the Daleks get him. That's it! What confuses me is why there is an unrelated story between this one and "The Daleks' Master Plan." Shouldn't they have aired it immediately after this one? Why not just make this the first episode of that serial? See you in a month, Daleks. We have to stop in Troy first...
