Arthur MacDonald, 85, is having an end-of-life crisis. His beloved, dying wife of over 60 years no longer knows who he is. His older brother still has all his hair and a wife almost half his age. The man his middle-aged daughter is dating has a ponytail. His teenaged grandson wants to cook desserts for a living. And his daughter wants him to move into Silvermine retirement home. Then Arthur meets the gorgeous, radical, 80-something-year-old Robbie and learns that nobody is ever too old to fall in love all over again.
