Successful playwright Al Pacino can't get any work done as long as he is pestered by his wacko wife Tuesday Weld. Making things worse are the couple's obstreperous children, many of them products of her previous marriages. Just as Pacino is completing his latest work, his wife walks out on him. That's the good news: the bad news is that he's saddled with a bunch of snot-nosed kids. Still and all, Pacino finds time to inaugurate an affair with his play's leading lady, played by Dyan Cannon, while attempting to juggle the stresses of opening night with the needs of the demanding, often obnoxious children.
