While Frankie's parents Tag and Pat visit for Christmas, Mike is less than thrilled. To make matters worse, the Hecks have a disagreement with them over Frankie's idea on how to celebrate the holiday without exchanging presents

Frankie's parents, Pat and Tag, invite the Hecks to spend a few days at their house to celebrate Thanksgiving together. But the festivities begin to fall apart quickly when Frankie's sister, Janet, and her family also join in, and soon the siblings are at each other's throats over their widely differing parenting techniques. Meanwhile, Mike tries to offer some advice to Axl on how to pick up girls when he witnesses his son trying to impress a pretty mini-mart cashier - and fails miserably; Brick attempts to prove his innocence when he is accused by Janet of damaging her daughter's expensive toy; and Sue is stoked when Frankie, Pat and Janet invite her to take part in their gossip sessions.

Frankie invites a couple of Marines to share Thanksgiving with her family; Axl gets good news; Sue tries to find the person who stole the chicken head from her uniform; Brick is mesmerized by a book.

Frankie tries to make Sue appear more popular on Facebook; Frankie's dad (Jerry Van Dyke) makes Mike listen to long-winded life stories; Brick and Axl try to create a viral video.

Frankie becomes emotional as the Hecks send Axl off to college, Sue waits for an important call from school, and Brick gets a new cell phone.

Axl looks for the right time to share news about his college classes; Frankie's dad reveals a gambling loss; Sue hides a secret; Brick determines to have lime-green Jell-O salad on Thanksgiving.

Frankie fears that her innocent flirtation with Axl’s friend has been misinterpreted, and Frankie’s dad, Tag, secretly asks Mike to help him study for his driver’s test so that he doesn't lose his license.

When Frankie's uncle contacts her dad hoping to make amends, Frankie and Mike are caught in the middle of their feud. Sue turns to Axl for advice when she is sent to detention for the first time.
