Mum is determined to find out who is responsible after she finds an inappropriate image on the family computer. Dad is scared at the thought of having a heart-to-heart with gran who is still staying with the family. Karen thinks she has won a large amount of money and starts to spend it.
Outnumbered is about a family living in South London, where the parents are "Outnumbered" by their three children. The parents constantly try to keep their children under control, but completely fail to do so. The father, Pete, works at an inner city school as a history teacher, whereas mother, Sue, is a part-time PA.
The three children are eleven-year-old Jake who worries about everything, from worrying about starting at his new school to the world being sucked into a black hole, seven-year-old Ben who constantly lies to his parents and always wants to watch Little Britain, and five-year-old Karen who constantly asks too many questions.
