One Step Beyond - Season 3 - Episode 12 - Where Are They?

In 1922 the town of Chico, California was pelted by rocks falling from an empty sky. A writer who called himself The Ghost took credit for the phenomena, but was never identified. Similarly, in 1917 a stranger appeared to government officials in Washington, D. C. and demonstrated a new fuel made from water that could power an auto engine. After his successful exhibition, the stranger vanished as quickly as he had appeared. The FBI and Secret Service searched for months and could never find him.
