The Human Telegram (1916)

To prevent a three mile journey around the mountain the telegraph wires at the construction camp have been strung over the precipice from the station on the mountain top. The operator is discharged when the superintendent suspects him of treachery and Helen is transferred to the station. Later, after the former operator has enlisted the aid of crooked brokers to use his knowledge in ruining the value of the road's stock, he receives an opportunity to get revenge on the superintendent.
