Mirren and Sutherland are Ella and John, an ordinary, elderly American couple. Suffering from the inevitable ailments of the old, they are nevertheless full of life and embark on a RV journey to Key West, to visit Hemingway's house.
So far, it could be an ordinary feel-good story, but from the beginning we get (or should get) the point that things are not what they seem.
The couple's son is highly distressed by their disappearance. When he walks into their house, we see lots of medical equipment, a clear sign that one or both spouses are in bad health.
Following Ella and John in their journey, we discover that John probably suffers from mild dementia, or memory loss at the very least. John also seems a bit of a flirt, chatting up all young waitresses with his "elderly professor gentleman" charm. This should make some final revelations come as no surprise.
Ella is a chatterbox, determined to give John the time of his literary life, with the long programmed but never executed visit to Hemingway's house. Ella is oblivious to the fact that John is not in the condition to care or understand much about the visit. We also understand that Ella is probably very seriously sick. Her phone call to a crying daughter is another sign that things are not right.
In the evening, during their stopover on their way south, Ella and John watch old photos about their lives. John can hardly remember who most people in the photos are. These quiet moments of lack of remembrance are perhaps the most heartbreaking.
The inevitability of life's end is treated with delicacy and even some humour and the movie is never gloomy or depressing, despite the subject matter. Still, expect to reach for your Kleenex toward the end.
