The thing about my folks (2005)

Ben's dad Sam shows up one night with a note from Ben's mother (Sam's wife of 46 years), that she has left. While Ben's wife and his three sisters try to find her, Ben takes Sam on a day trip to see a farmhouse that's for sale. The day trip turns into a road trip while dad and son explore their past, their relationship, and why Sam's wife might have left him. The road trip includes fishing, drinking, playing pool, sleeping under the stars, and frank discussion. Anger simmers close at hand, as do love and hope. Where Sam's wife is - and why she left - leads to the movie's resolution.
