Looking like death warmed over, Jack Lemmon plays the aging father of Ted Danson. Always proud of being able to fend for himself, Lemmon despises being reliant upon others, but his enfeebled state does not allow him his old independence. For his part, Danson resents having to care for his dad as he would for an infant. Things take an upward turn when a "Doctor Feelgood" (Zakes Mokae) enters the scene, pumping Lemmon full of self-confidence. But then Lemmon is stricken with cancer, an affliction that he can't jolly himself out of. As the reality of his imminent death strikes everyone around him, Lemmon retreats into fantasy, recalling the past happy events of his life as though they're happening here and now. The rest of the family humors their dying dad, and in so doing draws closer together than they've been in years. TV sitcom maestro Gary David Goldberg co-produced and directed Dad, and also adapted the screenplay from the novel by William Wharton.
