The 15-episode season kicks off with Sophie's sweet sixteen party, giving viewers an all access pass to the milestone celebration. When a case of sibling rivalry spirals out of control, Nick pulls on dad's heartstrings and his sense of theatrics to escalate the low key party she wanted into the blowout of the century, all to the dismay of shy Sophie.

In addition to Sophie's sweet sixteen, the new season will give viewers a behind the scenes look at the entire family's many adventures. From Gene's appearance on "Are You Smarter Than a 5th Grader?," to Gene filming a Japanese monster flick, to Shannon preparing for a role in a roller derby exploitation film, to Nick getting his own apartment, to Sophie fending off ill-intentioned teenaged boys, viewers will follow the Simmons-Tweed clan as they set out to prove, yet again, why they are the most non-traditional, traditional family in America.
