Glasgow is named European City of Culture, playing host to international artistic acts and Rab and Jamesie get into the spirit by starting a fight with a Peruvian folk band, for which they get sentenced to ten days in Barlinnie prison. On release Jamesie organizes his own 'sub-culture' tour, showing the seamy side of Glasgow, whilst Rab and his sons inadvertently expose the weaknesses of the city council to a pair of visiting European ambassadors.
