The show follows the adventures of an endearingly ignorant dad, Peter Griffin (Seth MacFarlane), and his hilariously odd family of middle-class New Englanders in Quahog, Rhode Island.
Lois (Alex Borstein) is Peter's wife, a stay-at-home mom with no patience for her family's antics. Then there are their kids: 18-year-old Meg (Mila Kunis) is an outcast at school and the Griffin family punching bag; 13-year-old Chris (Seth Green) is a socially awkward teen who doesn't have a clue about the opposite sex; and one-year-old Stewie (MacFarlane) is a diabolically clever baby whose burgeoning sexuality is very much a work in progress.
Rounding out the Griffin household is Brian (MacFarlane), the family dog and a ladies man who is one step away from AA.
In the eleventh season, the Griffins embark on a hilarious trip to Italy, Peter discovers that he has a vestigial twin growing out of his neck and a love triangle emerges between Stewie, Brian and Stewie's teddy bear, Rupert. Also, Peter and Quagmire (MacFarlane) become a singing/songwriting team, in the vein of Simon & Garfunkel.
Guest voices in the 11th season include Conan O'Brien, Jeff Daniels, Michelle Dockery, Tony Sirico, Yvette Nicole Brown and Gary Cole.
