Frankie encounters two perfect siblings and vows to make her children stop fighting and become a loving family. Meanwhile, Aunt Edie makes a costly mistake at the quarry and Mike considers firing her.

Mike's dream comes to fruition when Frankie's boss, Mr. Ehlert, offers him two tickets to the Final Four. Unfortunately, Frankie's uncle dies and the funeral is set for the same day, leaving the two in a battle and Frankie making Mike chose what life event is more important to him. Meanwhile, Sue gets Brick out of going to a birthday party by impersonating Frankie over the phone, but the plan hits a bump when Frankie needs to call and tell them that Brick cannot attend because of the funeral.

After failing to pay the electric bill on time, the electric company shuts off the Heck's power. This leads Frankie and Mike to cut down on their unnecessary expenses, including their cable TV. The kids take up other activities to fill the void, but Frankie and Mike have a hard time figuring out what to do. Meanwhile, Brick and his other socially-challenged friends have to go outside for recess when the school library shuts down.

Frankie is excited over being invited to an adult neighborhood Halloween party. But will she be able to get Mike to dress up in a costume, or will he have his own idea of fun? Meanwhile, a melancholy Sue's spirits are lifted when she discovers that Reverend TimTom is back in town and hosting a Halloween church event; things don't go quite as planned for Axl, his friends or their dates as they head out to an exclusive haunted house party; and Brick chooses a unique Halloween costume that is not easily defined.

Brick pleads with Frankie to leave him home alone when she runs errands.

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.

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 once again goes head to head with Brick's third grade teacher, Ms. Rinsky, when Brick gets a D on his math test and Frankie thinks poor teaching skills are to blame.

Meanwhile, while begrudgingly watching over their crusty, old aunts, Axl and Sue mull over a plan to accompany Aunt Edie on a search for a time capsule she buried when she was young.

Frankie and Mike are convinced that slacker son Axl will blow his interview with a football scout, which could earn him a scholarship to college. Meanwhile, Sue and Brick begin a texting marathon - and rack up some serious charges - when they discover that Aunt Edie accidentally gave them her cell phone; and Frankie tries to be completely attentive to the family's needs when she realizes that she's more considerate to outsiders than her own kin.

Aunty Ginny's funeral is the catalyst for Frankie's vow to begin celebrating all of the family's major life achievements. Axl mistakenly eats Brick's school map project and Sue finds out that a boy on the wrestling team has a crush on her.
