Valentine's Day unexpectedly finds Frankie and Mike home alone and ready for a romantic evening while Brick is away at his first sleepover, Sue goes to her first boy-girl party, and Axl has a big date night planned with some friends. But Cupid's arrow doesn't exactly hit the target, and the best laid plans soon begin to unravel.

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 points out to Mike that his social ineptness has been passed on to Brick, leading Mike to decide that both he and Brick need to be more social, and the Heck family BBQ is the perfect time to try. Meanwhile, Axl volunteers to clean the family pool in an attempt to get girls to stop by and swim and Sue tries to raise money for a local parish because her new friend, Reverend TimTom might be leaving in order to keep costs down

Frankie looks for a friend for Brick; Sue sneaks into an R-rated movie against Mike's wishes; and Axl and his band need a hot female for their music video and try to get stealth footage of their sexy biology teacher.

After being embarrassed over wearing a childish costume at a high school Halloween costume party and being ignored by the guys, Sue asks a flabbergasted Mike for his advice on what boys want when it comes to girls. Meanwhile, Frankie reluctantly volunteers to take Brick's socially awkward school social skills group trick-or-treating, and Axl and his friends devise a plan to trick rather than treat the neighborhood kids on Halloween.

Sue wishes for a big birthday bash for her Leap Year birthday. Meanwhile, Frankie learns that Mike has been taking care of a stray cat, Brick develops a crush at school, and Axl becomes fascinated with vacuuming.

Frankie has a difficult time describing herself during a job interview; Sue dispenses unwanted advice to Axl and his band mates; Brick joins the Prairie Scouts.
