Thirty-something teacher and professional shopper, Grace, has a passion for shoes. In fact they were responsible for her meeting her partner, Mark, when she speared his foot with one of her dangerously sharp heels whilst running for a train. Mark is the other passion in her life, or so she thinks... When he suggests they try for a baby - but is reluctant to tie the knot on their very long-term engagement - the cracks in her champagne lifestyle start to appear. As Mark becomes ever more controlling, Grace begins to see her blond and sexy boss, Tom, in a different light. A conventionally one-man woman who doesn't 'do' affairs, she suddenly finds herself in the midst of the sort of tangled lifestyle she has only read about in the celeb pages. Throw in the added complications of an untimely pregnancy, a case of mistaken identity and some pretty zany friends and Grace's life is thrown into turmoil. Retail therapy and even the comfort of her vast shoe collection can't help her out of this dilemma...
