At fifty-seven, photographer Kay didn't expect to fall head over heels in love, or get married, but the thing she thought she could always count on was Rose's friendship. She and Rose have known each other for over forty years and Rose was supposed to be Kay's maid of honor today at her wedding. So when she pulls her phone from the pocket of her bright yellow dress and sees the message, she's stunned: Kay, I hope today is wonderful. Please don't contact me again, Rose.
Kay is incredibly happy with her husband, Murray, who makes her feel so happy and loved. But without Rose in her life she feels lost. She and Rose have stuck together through it all; getting each other through tough break-ups, problems with children and losing Kay's beloved mum. Rose is Kay's person. How can she possibly want to say goodbye?
Murray encourages Kay to go back to a box of photographs she's kept of her dearest friends and family for many years. As Kay looks through the faces, she recognizes people faces she hasn't seen for years and wonders if they could help to her unlock the key to why Rose wants to say goodbye.
As Kay sets out to find the people she's let go, she hopes she will get a chance to convince Rose this doesn't have to be goodbye. But the journey will change her forever…
