Best Actress Academy Award nominee Charlotte Rampling (45 Years, 2015) and award-winning actor Tom Courtenay give career-defining performances in this emotional tour-de-force directed by Andrew Haigh (Weekend). Kate and Geoff Mercer have reached their twilight years with simple comforts intact: a cozy house, afternoon teas, meals with friends, and the rewarding accomplishment of a happy, longtime life shared together. But as they prepare to celebrate their 45th wedding anniversary, the couple's marriage is shaken to it's core when unexpected news suddenly threatens to change their lives forever.
