John Ritter ("Three's Company") and Katey Sagal ("Married...with Children") return to series television in this charming family comedy about a loving, rational dad who suddenly discovers that his two darling daughters have unexpectedly morphed into hormonally-charged, incomprehensible teenagers.

Paul Hennessy (Ritter) has grown accustomed to his stay-at-home wife Cate (Ms. Sagal) taking care of their son and two daughters. His job as a sports writer kept him on the road a lot during the kids' formative years. But when Cate decides to return to work as a hospital nurse, Paul takes a job as a columnist and agrees to make the duties of raising the kids a shared experience.

Paul fondly remembers the days when his daughters would sit on his lap singing silly songs, and he was their hero for scaring away monsters from under the bed. But those days are long gone.

Although not new to fatherhood, Paul is just a bit rusty on day-to-day interaction and discovers that he's grown a little out of touch with his kids - especially his daughters. His value has been reduced to a wallet and a ride to the mall. Sixteen-year-old Bridget (Kaley Cuoco, "Growing Up Brady," "Ladies Man") has matured into a beautiful and popular teenager with a different boyfriend each week and a taste for fashion that tends to be a little too revealing for her father's taste. By contrast, 15-year-old Kerry (Amy Davidson, ABC Family series "So Little Time") is intelligent and cute, but her lack of self-confidence has led her to hide behind a mask of sarcasm. Thank goodness for 13-year-old son Rory (Martin Spanjers, "Daddio"), fondly referred to as "The Boy" by Paul and Cate, who remains on the sane track...at least for the time being.

Though Bridget and Kerry still love their father, Paul has to come to grips with the fact that he is no longer the most important man in their lives at the moment. Dating boys and fitting in with their peers are the girls' top priorities. No matter what they do, Paul has one major rule that will never change - "If you make my daughters cry, I'll make you cry."

"8 Simple Rules for Dating My Teenage Daughter," based on W. Bruce Cameron's best-selling book by the same title, stars John Ritter as Paul Hennessy, Katey Sagal as Cate Hennessy, Kaley Cuoco as Bridget Hennessy, Amy Davidson as Kerry Hennessy and Martin Spanjers as Rory Hennessy.
