Alex Polizzi lends her considerable expert business skills to a failing family car repair garage in Ashton-under-Lyne, Manchester. Mum and co-owner Jan Lord despairs of getting the business out of theincreasing trouble it's in with too few customers and not enough work to fill the mechanics' days. Without improvement, she faces the nightmare scenario of losing her home and making her own children unemployed.

Alex Polizzi is called to an unusual family firm in dire need of help: Denver Mills, a working windmill in Norfolk.

Just before Alex arrives, a tragedy has struck. Three of the sails have crashed off the windmill, leaving the Abel family absolutely bereft. A business already in trouble has just hit rock bottom.

Alex finds a business that does not know what it is, with the site comprising of the windmill itself, a tea shop, gift shop, function room and rental cottages. She also finds a family that, although passionate about milling flour, are clueless about how to run a business. Relationships have also started to implode, with mother Lindsay not knowing anything about their finances and son-in-law Duncan angry that the family care more about milling than money. Alex has a huge challenge on her hands. She needs to get the family focussed, and fast.
