Neither Katie's parents nor Alan's grandparents think they should be dating out of their faith, so the desperate kids arrange a meeting between the two families. Things go from bad to worse during the uncomfortable dinner when obnoxious Uncle Willy and his wife Miriam turn up at the same Chinese restaurant the families have chosen as neutral ground.

Katie's father, already displeased that his eldest daughter Colleen is earning a living as a Rockette (his dream was for her to become a nun), refuses to give her permission to marry her boyfriend Charlie, saying that they are both too young and that Charlie has no job. Nevertheless, Colleen and Charlie elope, and Lt. Monahan refuses to speak to her since she is not married in the eyes of God. Also: The Silvers finally get a telephone.

When the family learns Katie's sister is pregnant and she and her husband are moving to California where he has a good job, they help Katie plan a shower for her, but Lieutenant Monahan is still hurt that Colleen was not married in the Church. But a chat with Cousin Jacob, who has taken a job painting the Monahans' apartment, may convince him of what's really important. In the meantime, Nicholas and Sid teach George and Jules the finer points of betting on the ponies.
