Filmmaker Alex Beckstead's grandparents, Bill and Peggy Heiner, are part of the backbone under America's blue collar. Grandpa's constant drinking since he retired is tainting their Phoenix oasis. As much as he loves Grandma, he can't seem to put down the bottle and make their life-after a trying half century-as perfect as he would like. This complicated, affectionate story of one American couple explores how they have stayed together for 50 years in spite of themselves.
