Dad (1989)

A busy, "always-on-the-run" executive learns during a meeting that his mother may be dying and rushes home to her side. He ends up being his father's caretaker and becomes closer to him than ever before. In the process, he teaches his father to be more independent which causes problems with the man's wife. Estranged from his own son, the executive comes to realize what has been missing in his own life.
