For West London girls Sal and Ann Storey, 1957 should have been one of the happiest years of their lives. Instead, the sisters' world is turned upside down when two family tragedies strike in quick succession. Left to run the family's sweetshop with their grandmother, Sal discovers she has a flair for business - but it doesn't make up for everything she and Ann have lost. When Sal meets handsome taxi driver Bob Beck and falls deeply in love, it seems that her luck is changing. Bob becomes her one constant as she struggles to keep the business afloat, and as Ann finally uncovers the guilty secret she's been carrying for so long; a secret which could have explosive consequences for the sisters. The last thing Sal needs is for Bob's scheming ex-fiancee Kate to reappear in his life - especially as Kate is preparing to make a stunning revelation; one which could destroy their relationship for good...
