Set sometime in the 1950s, the show's foundation rests on an elite team of crime scene investigators, mostly residents of the fictional town of Pleasantville. They are skilled in the fields of biology, chemistry, forensics, ballistics, medicine and basic paperwork management. Every week, the team tackles a myriad of complex cases, ranging from murders to heists that plague the town. In addition to solving crimes, the investigators are beset with their own personal tragedies to add an element of melodrama in each episode.
