The Edge of Love (2008)

Vera Phillips and Dylan were teenage loves; fast forward ten years and the two reconnect in London. She's working as a singer whilst he's churning out scripts for government propaganda films, and living off the last in a long line of infatuated women. The two former lovers feel the thunderbolt once more, but Thomas is now married to the adventurous Caitlin. Despite their love-rival status, the women form a surprising friendship. Desire and guilt are complicated by love and friendship in this real-life tale, set in London and the majestic Welsh countryside.
