THE KILLER WASTES NO TIME, WITH A SUDDEN AND SHOCKING MURDER, ON ABC'S "WHODUNNIT?"

The 13 Guests Arrive and Move in, Only to Find Themselves Thrown into the Game Immediately

"High Voltage" - Thirteen strangers arrive at the sprawling estate called Rue Manor and are met by Butler Giles, who welcomes them to their new residence where they will play out their high stakes game of murder and intrigue. Before they can even settle in, the guests are thrown straight into the game after making a startling and gruesome discovery -- one of their own, bloodied and dead on the floor of the great room. The body lies in a pool of water with a live wire sending electric currents through the corpse. Who did it? How was it done? The remaining guests must use their investigative skills and strategy in order to solve the crime -- otherwise they'll become the next victim -- on "Whodunnit?," SATURDAY, JUNE 29 (10:00-11:00 p.m., ET) on the ABC Television Network. (Rebroadcast. OAD: 6/23/13)

Note: This program replaces "20/20 Saturday."

"Whodunnit?" is an interactive series that puts 13 amateur slueths' investigative skills to the test in a riveting mystery reality competition. Players 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 players will form alliances in the competition, while others will choose to go it alone in their quest for the grand prize of $250,000. The contestants will be guests 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 player's demise, until only three are left. In the final episode, one player will unmask the killer and take home the $250,000 prize.
