Anthony E. Zuiker, creator of the CSI franchise, brings the world of murder and intrigue to his first primetime reality series, "Whodunnit?". The series puts 13 guests' investigative skills to the test in a riveting mystery reality competition. Guests will use a variety of crime scene investigation techniques to meticulously uncover evidence in a series of puzzling murders and to ultimately reveal who among them is the killer. Some guests will form partnerships in the competition, while others will choose to go it alone in their quest for the reward of $250,000. The guests will reside on a glamorous estate called Rue Manor with a steward, Butler Giles (Gildart Jackson), and each week must solve a new crime in order to advance in the game. Failure to solve the crime will lead to a guest’s demise, until only three are left. In the final episode, one guest will unmask the killer and take home the $250,000 reward.
