Madhavan stars as Manohar who moves in to a new flat (13, B) along with his huge family. His wife Priya (Neetu Chandra) is an ideal daughter-in-law, she doesn't throw tantrums, loves her mother-in-law and even watches TV serials along with her. However, Manohar becomes increasingly suspicious of ominous sings in the new flat. One day, a new serial is aired on TV, again on channel number 13. To Manohar's shock, all the incidents portrayed in the serial are exactly similar to their own lives. Even more surprising is that this serial governs the fate of the entire family. So, what's this mystery behind the TV Serial? Is it a way of communicating with spirits and ghosts? How does Manohar manage to solve the problems? That forms the rest of the story.
