在法國巴黎經營咖啡店「Happy People Read and Drink Coffee」的Diane，看似擁有美滿的生活。然而，突如其來的一場車禍，瞬間奪走了丈夫與年幼女兒的性命。無法從過往的記憶走出來的她，疏遠朋友與家人，也關上了心房。
Diane, owner of Happy People Read and Drink Coffee, a cosy coffee shop turned library in Paris, 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. Along windy shores and cobbled streets, Diane falls into a surprising and tumultuous romance. As she works to overcome her painful memories, Diane and Edward's once-in-a-lifetime connection inspires her to love herself and the world around her with new-found inner strength and happiness. But will it last when Diane leaves Ireland, and Edward, for good?
