The Veil (1958)

A young man, badgered by his father to work in his aviation company, sees a vision of a man while on a routine air-flight. The vision tells him to go to a certain location and he does...in a trance. He is stopped by his copilot before their plane crashes. Later on he sees something that makes him think he knows who the vision was. He must go "Behind The Veil" to find out if he's correct.
