Written by miner, union organiser and activist Lewis Jones, Cwmardy is the story of Big Jim, collier and Boer war soldier and his wife Siân as they strive to wrest a decent life from dire conditions despite the exploitation of mine owners and the apathy of a distant and uncaring political class.

In We Live, their son Len emerges as a sharp-thinker and dynamic political organiser. He is influenced by Mary, a teacher, and the politics of the Communist Party, which will become central to his work both underground and with the union. It will ultimately lead to his decision to leave and fight in the Spanish Civil War.

Echoing the European classics of Zola and Maupassant, the lives of Big Jim, Siân, Len and Mary reflect the changing times of a turbulent world which will see them survive strikes, riots, and biting poverty while the dark shadows of a world war gather to offer an uncertain future.
