Mike and Frankie's plan for a simple Christmas are dashed when Frankie's parents show up and stay for 12 days, spoiling the children and never giving Mike a minute of freedom.

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's bickering parents come for Thanksgiving, along with two special guests. Axl's football comeback may be postponed by a broken heart, Sue's mascot head is stolen, and Brick is fascinated by a new book.

Frankie turns to Facebook to help make Sue more popular, Axl and Brick try to make a viral video with bunnies and kittens, and Frankie's dad tries to share his "wisdom" with Mike.

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.

It's Thanksgiving, and Axl looks for the right time to say he dropped three classes, Frankie's dad looks for the right time to say he gambled away their vacation money, and many surprise visitors arrive at the last minute.

Frankie fears that her bad remark about Axl's hot friend may have been overheard. Sue takes Brick to a Planet Nowhere convention. Tag asks Mike for help on his driver's test.

Frankie and Mike find themselves caught in the middle of a long standing family feud when Frankie's Uncle Dutch contacts her dad, Tag in an attempt to reunite and bury the hatchet with his estranged brother. Meanwhile, a fearful Sue receives her first detention ever for being caught going off campus for lunch and seeks advice from Axl on how to survive the ordeal unscathed.

At the annual homecoming tailgate, Frankie worries that her mother will ruin things, Sue takes a familiar role, Axl is sick as a dog, and Mike asks Brick to help him win the cornhole tournament.
