Anita's mother was the mermaid in the Belle Vue Fair Freak Show. Into their lives came Paddy Riley, a young Irish lad whose motto was 'the only crime in life is not to take up a good opportunity'.
The opportunity was Anita's mother - hungry for love and romance. Their secret is safe until young Anita, their go-between, spins a jealous lie that tragically catches them all. Now grown with children of her own, Anita has found a kind of peace with a sweet husband, and the past is past. Until that is, a man not unlike Paddy Riley comes to their town. It's an 'opportunity' that Anita cannot, for the life of her, seem to resist.
