When Steven's recently divorced brother Rob arrives with his son and daughter for a visit, the Keaton's become a sounding board for their relatives' family problems. In the wake of his divorce, Uncle Rob has given up his job as a CPA and is enjoying ""working in the great outdoors"" as a telephone repairman, a considerably less lucrative career which his teenage daughter Marilyn feels is a great hardship on the family, and particularly on her.

When Uncle Rob's daughter Marilyn stays out all nite with a Marine she meets while visiting the Keaton's, the family becomes painfully aware of her deep-seated anger with her father over her parents' divorce. Rob is left feeling stunned and hurt, as the Keatons begin to realize that communications between their beloved relatives have completely broken down.

The following morning, when Marilyn comes home and flatly refuses to talk to her father, the Keatons jump in to try and help. While Elyse shepherds everyone out for ""a walk"", Steven stays behind with Rob to discuss Rob's feelings about his guilt over the divorce and his fears about confronting his daughter. Things don't improve when Marilyn tries to leave a day early for her mother's house and ends up in a screaming match with her father.

Deeply troubled, Rob finally forces himself to corner Marilyn and press for an honest talk. And as he opens his heart to her, she finds herself unable to resist the power of his love.
