Danny and Kathy, with three children along, take a delayed honeymoon in Las Vegas but Danny draws the family's ire by entertaining spontaneous crowds against his pledge that this was to be a non-working vacation.

Terry has been running the household since her mother's death: managing meals, shopping, laundry, and looking after her father. Kathy tries to explain gently that she is taking over running the house, but Terry isn't giving up her position without a fight.

Danny's Uncle Tonoose comes to town to meet his new niece-by-marriage, Kathy, which is actually an inspection to determine whether she will be officially accepted into the family. Unfortunately, Uncle Tonoose's shabby treatment of Kathy seems to indicate that he does not approve of her.
