When the Welsh poet Dylan Thomas and his flirtatious wife Caitlin sweep into war-torn London, the last thing they expect is to bump into Dylan's childhood sweetheart Vera. But despite her joy at seeing Dylan after so many years, Vera is swept off her feet by a dashing officer, William Killick, and finds herself torn between the open adoration of her new-found beau and the wily charms of the exotic Welshman. William joins the war effort abroad and Vera finds herself spending more and more time with Caitlin while constantly having to fend off the advances of the amorous poet. When William returns, the incestuous bond between the trio sends him into a jealous rage.
