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.

After realizing that no one keeps their New Year's resolutions, Frankie decides that they will be assigned anonymously to each family member, and an all-you-can-eat buffet feast will be the reward for those who can abide by their chosen resolution for a week. But chaos soon ensues when Frankie must spend more time with Brick, Mike needs to smile more, Axl has to keep his bedroom clean, Sue needs to stop trying out for things she'll never make, and Brick must stop reading all of the time.
