Leonard takes Alex to the town where he met Alex's mother, but there is a problem: the town's population has vanished overnight. A corpse and the site where a man was murdered seem to vanish without leaving a trace. After seeing strange lights in the sky, the Blackes have reason to suspect that aliens might have abducted a woman.

Alex is hired to escort a notorious criminal who always escapes from his captors. Alexander (Hal Linden) suspects a businessman, Granville Stuart (Peter Haskell), of being a murderer. However, this master of escape is later believed to have leaped to his death from a heavily guarded bell-tower cell.

Alex comes to the aid of his former assistant, Louise Richmond, whose husband has blown the whistle on a conspiracy between his company and the Government. When Alex suspects General Wersching (J.D. Cannon) is accepting bribes from a corporation doing business with the government, he enlists Wersching's assistant, Major Crawford (Nancy Grahn) to help him uncover the truth.
