Frankie's plan to have an idyllic family Thanksgiving backfires when Mr. Ehlert demands his staff work over the holiday. Brick goes missing in a corn maze.

Mike begrudgingly invites his brother, Rusty, who is temporarily living in a tent, and his father, Big Mike, who has recently broken his hip, to join him for the annual Heck family Thanksgiving. But when Frankie observes the macho Heck men's non-communicative nature, she encourages a not-so-receptive Mike to engage them in a real conversation and express their feelings. Meanwhile, Brick is ecstatic when he discovers that Bob is bringing his girlfriend, Linda - the local librarian who loves books as much as Brick does - to Thanksgiving; and Sue wants to start a mother-daughter tradition of baking a pie for the holiday, but ends up getting more sliced up than the crust.

Misfortune plagues Brick after he finds a four-leaf clover; Frankie seeks a caregiver for her aunt; Axl struggles with a prom-date dilemma and is also dismayed to learn that Sue is Darrin's prom date.

The Hecks are pleased to learn that Mike's brother, Rusty is getting married. However, the joy is short-lived, when they discover that the wedding is to be held at their house. Meanwhile, Brick cannot attend a party that same day, due to the nuptials.

Frankie worries Mike is tiring of her as their 20th anniversary draws close; Sue tries to get Axl and Brick's help planning a party for their parents; Axl spoils the end of a book for Brick.

Frankie invites Mike to join her on a trip to Des Moines, Iowa for a convention about her dentist office's transition to a new owner; and Axl informs a disapproving Sue that he's moving into her dorm room. Meanwhile, Mike's dad agrees to watch Brick while the parents are out of town.
