Annie and Marina have shared a London flat for years, and in spite of very different outlooks on life have become very close. Annie, a newspaper columnist, is unsure of herself and eager, longing to find the man of her dreams who will always give her the life she has always wished for. Marina works in the City, is beautiful, confident, and in spite of having the pick of the most eligible men in the financial world, is content to be single and concentrate on her career. So of course it's Marina who falls, totally unexpectedly, head over heals in love with the last man on earth you'd expect to see her with. And Annie is left, feeling very alone, facing the prospect of her worst fears coming true.
