Future Lives

A doctor using unusual hypnotic techniques with his patients accidentally contacts a human being from another planet. Through this person he becomes aware of a large colony of these people living on Earth, a knowledge which causes him a lot of complications as these people definitively do not want to be known.
The doctor is hit by a car, not quite accidentally, and wakes up in hospital on a distant planet.
After recovering, thanks to the advanced alien medicine, he continues his work there, trying to look into the future through the minds of hypnotized persons.
The doctor becomes very successful in his work-which causes him new problems as some scheming politicians do not want the future to be known too early.
