London. A guy meets a girl. But this is not a love story. Not a traditional one, at least. She has petroleum coloured hair, she's a bit 'wacky, talkative, pushy. He, a brilliant young journalist trapped in an unrewarding job. Together they plunge to the discovery of their city, turning every date into a little adventure, learning to know each other and dreaming about the future. But, one morning, she disappears. Without a note, with no explanation. Every object related to her seems magically vanished. Finding her, for him, becomes an obsession leading him to doubt himself, to face uncomfortable truths, to re-evaluate his choices, his relationships with other poeple, the whole concept he has always had of himself and his world. Who really is Leila? How much is she real?
