Except today, Ned's gay son Jonah wants to go to a college party, his wife is bringing home their elderly father to live with them, and his outrageous boss seems to have become even more crazy and demanding than would even seem possible. As his wife tries to take care of her father reconnect with him, Ned tries to reconnect with Jonah, and then without trying, he seems to have formed a connection with his co-worker. If he can get through days like these, he should be able to get through anything else life throws at him. Ned and Jeannie: married 19 years. Ned has trouble with Garrett, his boss at the cable show he writes, and he's ill-at-ease with his older son Jonah's coming out and wanting to go to a high-school gay student society prom. Jeannie puts work on hold while she attends to Ernie, her sour and mean-spirited father whose ill health forces him to move in with them. While Jeannie taxis the boys, goes to one son's recital, sees to her father's needs, and fixes meals, Garrett assigns Ned to rewrite a script with Robin, an uninhibited, unattached colleague who offers no-strings fun. Can this family hold together while a chicken hawk circles Jonah, Robin inveigles Ned, and death hunts Ernie?",
