After drifting apart emotionally over the years, two single siblings — Wendy (Linney) and Jon (Hoffman) — band together to care for their estranged, elderly father, Lenny (Philip Bosco), who is rapidly slipping into dementia. Wendy and Jon first travel to Sun City, Arizona to attend the funeral of their father's girlfriend of 20 years. When they arrive, they are told that their father signed a non-marriage agreement and will not have rights to any of her property. They then move him to a nursing home in Buffalo, where Jon is a theater professor working on a book about Bertolt Brecht. Wendy, who is an aspiring, but unsuccessful, playwright, moves from New York City to help establish their father in Buffalo.
