Comedian Rob Brydon explores Welsh identity and tries to discover what makes his patriotic countrymen so defensive. Along the way, he talks to a host of Welsh celebrities, including Griff Rhys Jones, Goldie Lookin' Chain and actress Ruth Jones, as he examines the national psyche, in particular questioning his own belief that the Welsh have a natural leaning toward pessimism. Rob also constructs a stand-up routine of Welsh-based material which he tries out in surprise appearances at comedy clubs around Wales.
