This dark figure has diabolical plans for captured scientist, Dr. Hammond, and his War Department weapons of mass destruction. Upon the Phantom Shadow launching a treacherous missile attack on key locations in the United States, the government takes action. There is only one man to call, Agent 236, an elite government agent. Agent 236 has been dispatched to launch a rescue mission. Of course, nothing ever goes as planned. Our hero finds himself on the way to Hammond Castle, Dr. Hammond's research facility on a remote island. The Phantom Shadow's trap has been sprung. Along the adventure, Agent 236 is befriended by a spunky, sarcastic gas station attendant who just happens to have pinup girl good looks. She also just happens to be looking for action, and excitement. Luckily, Agent 236 is the man of her dreams. Agent 236 puts the station attendant and her tow truck into service in pursuit of the Phantom Shadow.
