- Narrator: [Opening Narration] In a decaying lobster port in Maine, David Vincent searches for a man who has seen the Invaders: a fisherman named Nat Greely, who has taken one of their weapons - a strange, metallic disk. For a day and a half, Vincent has combed the tiny waterfront town but Nat Greely has disappeared.
- Narrator: [Epilog Narration] A trip to a nightmare world. A committee disbanded. Another defeat, another hope lost for David Vincent - maybe. Or maybe it's a hope begun.
