Dave makes a run for city council, working hard to earn Calvin's support, only to have a controversial photo threaten to derail his entire campaign.

A near-accident awakens Dave's sense of civic duty, prompting him to team up with Calvin to try to improve the safety of their community; a trip to the county fair turns into a nerve-racking adventure for Malcolm, Marty and Grover.

Tina spends time with the charming new minister she helped select for her church; Calvin suspects the man may be coveting more than just job security; Marty gets a surprise when he finally meets his disruptive, new upstairs neighbor.

Dave's patience is tested when Gemma's freeloading sister suddenly shows up with plans for an extended stay; Calvin grows frustrated that Malcolm is still living at home.

Calvin reluctantly agrees to let Marty create a website for his auto shop in hopes of drumming up more business; Dave makes it his mission to prove to his son that there's more to life than his favorite gadgets.

Adam has been operating under the assumption that his three children are little angels, but when his wife decides to rejoin the workforce after being a stay-at-home mom for 13 years, and he starts taking on more of the parenting responsibilities, he's quickly disavowed of that notion. Kate, a preteen, is a master manipulator and excited to take advantage of her father's naivete; Teddy spends too much time with his hands down his pants; and Emme frets over school. After recovering from the initial shock -- and with the advice of equally stressed parents Marie and Lowell -- Adam is confident he can lay down the law and keep the house in order.

For most parents, parenting is hard, but for Kay, a caustic, take-no-prisoners casino pit boss, and husband Mike, a handyman and uncultivated guy's guy, parenting may as well be advanced calculus. Dealing with the demands and egos of three high-IQ children would be tricky for any parent, but it's especially hazardous for two working stiffs who barely got through high school. Mike and Kay are committed to bringing some normalcy to their kids' hectic, unconventional childhoods, but these geniuses don't make it easy.

Jackie, a single suburban mother, is shocked when her estranged sister, Elizabeth, her sister's outrageously wealthy, big-hearted husband, Javier, and Javier's fiercely loyal assistant/driver/friend, Luis, land on her doorstep in need of a place to live after the couple's money dries up. Though class differences may separate the women, and the size of the house and the number of people living in it will test the limits of family ties, the familial bond of sisterhood might be the catalyst they need to restore their relationship.

Young parents Dave and Rebecca are ready to reclaim their life after years of diapers and sleepless nights. However, things take an unexpected turn when Dave's parents show up unannounced and broke after having mismanaged their former wealth, especially after his mom needed knee surgery -- without insurance -- following a spin class accident. Dave, ever the loving son, has no choice but to open the door to the people who gave him everything. But these boomerang parents aren't great with boundaries, and the question of who's parenting whom quickly becomes blurred.
