Complete story — includes the ending

Betty is diagnosed with terminal lung cancer and refuses treatment despite Henry and Sally's objections, believing it would only prolong the inevitable; she gives Sally a letter with burial instructions and expresses pride in her. Pete dines with his brother Bud and reflects on their family's history of infidelity. Duck Phillips offers Pete a position with Learjet in Wichita, Kansas, promising a fresh start; Trudy agrees to relocate, they reconcile, and McCann buys out Pete's contract in exchange for securing Learjet and access to its corporate clientele. Don continues west and becomes stranded in rural Oklahoma when his car breaks down. He reluctantly joins a veterans' fundraiser to repair a home and, while drunk, confesses to a group of veterans that he accidentally caused his commanding officer's death in Korea, and is surprised to receive sympathy. However, the same men later assault him, suspecting he stole their fundraiser money. Don realizes a young hustler, Andy, took it; he retrieves the cash, warns Andy against dishonesty, returns the money to the veterans, then gives Andy his car. Free of all material possessions, Don smiles as he waits for a bus.
