From CSI creator Anthony E. Zuiker, Whodunnit? is a mystery reality competition pitting 13 amateur sleuths against each other in a quest to solve a series of puzzling murders. Over the nine episodes, the contestants will employ a variety of crime scene investigation techniques to uncover evidence that will ultimately reveal who among them is the killer. While residing on a glamorous estate, the participants can choose to form alliances or go it alone as they must solve a new crime each week in order to advance to the next round. Once the field has been whittled down to three, one player will unmask the killer in the final episode to take home the grand prize of $250,000.
