The life of legendary poet Dylan Thomas is told through the stories of two free-spirited women who loved him in this fiery romantic drama set in wartime London. As World War II rages on, poet Thomas (Matthew Rhys) reconnects with an old flame, Vera (Keira Knightley), who is working as a cabaret singer while he is writing propaganda scripts for the government. When his wife Caitlin (Sienna Miller) learns of Vera s re-entry into her husband s life, what could have been a heated battle between the two women instead blossoms into an unlikely camaraderie, as each finds their tempestuous nature and shared affections reflected in the other. But with the return home of Vera s former lover William (Cillian Murphy), a rift begins to develop that threatens to destroy the seemingly idyllic lives they ve started to build with each other. And as the war continues, the two women s devoted friendship may be the one thing that endures them as their lives are changed and their loyalties tested during this most tumultuous time in history.
