Where The Lights Shine Brightest

The man has recurring dreams of blinding lights and experimentation on him, and somehow the way he looks never changes, no matter what he tries.
There is a woman from those dreams who he almost meets all over the world, she is always leaving as he arrives, and he never gets to speak to her.
Then he meets the sister of his dead fiancée on the Tube, and he starts to fall for her.
But now his flight, which has both women on it has been hijacked and he's in trouble with the hijackers. What is behind the hijacking? Is it all connected somehow? Will he manage to shake his dreams off and deal with the women? Will the blinding lights be explained?
