Frankie and Mike's romantic anniversary get-away is ruined by various family matters, including Brick being sick, Sue being lovesick, Axl just getting his learner's permit, and two psychotic aunt's and their dogs.

When Axl accidentally breaks down the front door, Mike insists that, he fix it in order to teach him a lesson, which leaves the Heck house wide open for days.

Frankie is worried that Axl's going to get his heart crushed again when his on-again/off-again girlfriend, Morgan (Alexa Vega, "Spy Kids," "Ruby & the Rockits"), re-enters his life and tries to mold him into the man she wants him to be. Meanwhile Brick learns what it means to be a mother hen when he has to watch over a baby chick for a school science project.

Frankie comes up with a plan to stay on top of her kids' schedules; Brick's new teacher (Doris Roberts) accuses Frankie of being overprotective.

As the Super Bowl approaches, Mike is thrilled when Brick takes his advice and studies up on football in order to understand and talk the sport. But Axl thinks his little brother is taking over his turf by being Mike's football buddy - a position Axl used to cherish.
