In the pivotal Welsh town of Port Talbot in 1942, a young Richard Jenkins finds himself caught between the struggles of his family and the devastating war, yet discovers an opportunity to express himself through drama that changes his life forever. With the guidance of Philip Burton, a teacher who sees potential in the wayward schoolboy, Jenkins' natural talent is nurtured, but so too are the complexities of their relationship - one marked by mentorship, love, and ultimately, loss.
