Family Guy follows Peter Griffin the endearingly ignorant dad, and his hilariously offbeat family of middle-class New Englanders in Quahog, RI.

Then there are their kids: 18-year-old Meg is an outcast at school and the Griffin family punching bag; 13-year-old Chris is a socially awkward teen who doesn't have a clue about the opposite sex; and one-year-old Stewie is a diabolically clever baby whose burgeoning sexuality is very much a work in progress. Rounding out the Griffin household is Brian the family dog and a ladies' man who is one step away from AA.

The Ark takes place 100 years in the future when planetary colonization missions have begun as a necessity to help secure the survival of the human race.
