Happy-go-lucky advertising executive David Basner, who recently got a promotion at his Chicago ad agency, returns to work from a vacation. He is carefree, until his parents split up, after 36 years of marriage. It soon becomes apparent that he must care for his aging, bitter father Max, as well as support his emotionally fragile mother Lorraine, especially since his father has also just been fired from his 35-year career in the garment industry. Although his ex-girlfriend, Donna, is sympathetic, she also tells him he needs to "grow up," but David fears that if he tried to be less child-like, his advertising work could be adversely affected. At work, David is developing a commercial for Colonial Airlines, owned by the rich and bullish Andrew Woolridge. A successful ad campaign would likely gain David a promotion to partner in his company. David develops a relationship with Woolridge's daughter, Cheryl Ann Wayne. His father is well aware of David's playboy nature. Asking at one point whether his son is in bed with a woman, Max adds: "Anybody you know?"
