Here is the synopsis of the show that Fox sent out: 
Raising a teenager can be a challenge. Raising five at once means all-out war. The quintuplets were a blessing for CAROL (Rebecca Creskoff) and BOB (Andy Richter) when they were first born � an adorable gift of abundance, they graced many a magazine cover promoting everything from applesauce to condoms. Their teenage years, however, have been less than kind. The quints are no longer the precious little tykes they used to be. Now they are three boys and two girls of varying sizes, looks, intelligence and social skills.  Torn between their dependence on each other and their need to develop their individuality, the quintuplets must deal with the problems of living their teenage years as one of five siblings. 

PENNY (April Matson) is the awkward, unpopular girl at school who eats lunch alone and hates being a quint. Luckily her sister PAIGE (Sarah Wright), the beautiful, popular daughter, has enough self esteem for the both of them. Meanwhile, the brother�s personalities are just as strong.  PATTON (Ryan Pinkston), the shortest brother, wants desperately to score with a girl and PEARCE (Johnny Lewis) is the oddball of the group. PARKER (Jake McDorman) is the brother who has it all, good looks, hot girls, and unfortunately two brothers who embarrass him at every turn.
