Y Sŵn

In 1979, when Margaret Thatcher's first government breaks a promise to establish a Welsh language television channel, a wave of civil disobedience follows. One man - Gwynfor Evans - threatens to starve himself to death unless the government comes good on its manifesto pledge. The reimagining of one of the most colourful chapters in contemporary Welsh history.
