Hamilton is a silk manufacturer on a Seattle-to-New York train to deliver an important shipment for his company. He's got to face Hohl, the leader of some unscrupulous businessmen who want to corner the silk market. On the train are the usual slice-of-life people including Kibbee, a
railroad detective, Digges, an ailing professor going to New York's Rockefeller Institute, and Terry, his daughter. The elements for an effective programmer are all in place, but the dialog and Hamilton, who is woefully miscast, leave much to be desired.
