Darren McGarvey explores Scotland's dangerous love affair with alcohol. At the liver unit in Dumfries and Galloway Royal Infirmary, Darren shadows Dr Mathis Heydtmann to see first hand how Scotland's obsession with alcohol is causing us deadly harm. In Dundee, he meets psychologist Suzanne Zeedyk to confront his own battles with alcohol and try to understand his problematic relationship with it. He also talks to historian Thora Hands to discover whether Scotland has always been a nation of hard drinkers.
