Plot synopsis
Aliens abduct David, a 12-year-old boy, and fill his brain to overflowing with space charts during tests they performed on him.
As it is too risky for the aliens to return him to 1978, they return him to his family eight years later, but he has not aged a day.
David becomes a freak show for scientists and eventually he realises that they will never leave him alone if he stays.
He asks the aliens to transport him back to his time telling them that he is willing to take the risk.
During this process, he learns to navigate the flying saucer through space and time, hence the title of this film.
My comments
David sees how his family’s life has progressed since his disappearance. He knows that if he goes back to the moment he was abducted, it will create a new timeline with him as part of the family.
It is assumed that the original branch will collapse if this new one is created.
