The passion and pathos of legendary poet Dylan Thomas is told through the lives of these two women. Vera Phillips (Keira Knightley) and Dylan (Matthew Rhys) were childhood sweethearts in their homeland Wales. Ten years later the two meet again in war-time London. She's working as a singer whilst he's churning out propaganda scripts for the government in aid of the war effort. The two feel the thunderbolt once more, but Thomas is now married to the adventurous Caitlin (Sienna Miller) and Vera is embarking on a romance with the intense but loyal William (Cillian Murphy). Despite their love-rival status the women form a strong friendship and when William goes to war the remaining trio form a fierce but unavoidably complicated bond. Broken promises, betrayal and the shadow of war provide a vivid setting for The Edge Of Love.
