Dotty and Stella have lived together for the last 31 years on the coastline of Maine. But when Dotty takes a fall and 911 has to be called, her granddaughter Molly wonders if her Grandma's "friend" Stella can truly care for Dotty anymore, and arranges for Dotty to live in a nursing home. Unwilling to live without one another, Stella and Dotty hit the road to Nova Scotia to get legally married. But the road is long and rough, and Stella begins to wonder if she really can take care of Dotty in their old age. After 31 years, can they keep their family together?
