The real story behind Dunnes Stores, the most quintessentially Irish shop of all, and the family drama behind it

This is the story of the extraordinary family behind one of Ireland's most famous businesses, Dunnes Stores, over three generations and covering nearly 80 years of retailing but going back as far as the 19th century.

With drama worthy of the popular TV drama Succession, a real-life Irish family drama shows the children of a dominant founder argue as to who should run the supermarket empire after his death and take the money from it, and how they dealt or not, with addictions and ill health, including alcoholism.

This is the story of excess, success and failure.
