A few days after Christmas in a small suburb outside of L.A., pairs of a man's pants hang from the trees. The pants belong to Howard Young, a prominent history professor, recently diagnosed with Alzheimer's disease. Howard's wife, Annie, summons their daughter, Ruth, who quits her job and arrives home to find her parents' situation worse than she'd realized. She throws herself into caretaking: cooking dementia-fighting meals (a feast of jellyfish!), researching supplements, anything to reignite her father's once-notable memory. And when the university finally lets Howard go, Ruth and one of her father's handsome former students take their efforts to help Howard one step too far.
