A wife, mother, and owner of Happy People, a cosy coffee shop-turned library in Paris, Diane seems to have the perfect life. But when she suddenly loses her husband and daughter in a car accident, her life is overturned and the world as she knows it disappears. Trapped by her memories, Diane closes her shop and retreats from friends and family. One year later, she moves from Paris to a small town on the Irish coast, determined to heal by rebuilding her life alone, without anyone's help or pity - until she meets Edward, a handsome and moody Irish photographer.
