High-schoolers David and his sister Jennifer lead very different lives: Jennifer is shallow while David spends most of his time watching Pleasantville, a black-and-white 1950s sitcom about the idyllic Parker family. One evening while their mother is away, David and Jennifer fight over the television, breaking the remote control.
A mysterious TV repairman arrives and, impressed by David's knowledge of Pleasantville, gives him a strange remote control before departing. When they use the remote control, David and Jennifer are transported into the black-and-white world of Pleasantville, finding themselves in the Parkers' living room. David tries to reason with the repairman, communicating through the Parkers' television, but the repairman declares that the world of Pleasantville is better than the real world and they should be lucky to live in it.
