It is 1999. Kate Lambert, a grieving, semi-alcoholic film student, invites an elderly woman to take part in an oral-history documentary. The woman, Jean Culver, declines, but makes her a bizarre counter-offer: if Kate can stay sober for four days, she will tell her a story. And if she can stay sober beyond that, there will be another, and then another, amounting to the entire history of one family’s life.
