This Monday CBS is airing a very unique episode of crime procedural Hawaii Five-0. Viewers will have the opportunity to choose the ending of the episode in real time. Check it: The mystery begins when the team must investigate the death of an O’ahu State University professor. His Boss, his Teaching Assistant, and a Student who he busted for cheating are all viable suspects. After each of the suspect’s motives is revealed, the network will advise viewers to vote who they think should get charged for the crime. There are two ways you can vote: go to CBS.com or hop on Twitter and use the hashtags #theBoss, #theTA, or #theStudent to voice your opinion. The votes will be tallied immediately and the most popular ending will become part of the broadcast, says CBS. And get this: separate voting will occur for East/Central and Pacific Time zone broadcasts, meaning each side of the nation may see different endings. All three endings have been shot, obviously, and CBS promises to make them all available to view on CBS.com after the broadcasts have aired.

“I’ve always felt the most fun aspect of watching a mystery is trying to figure out whodunit,” says exec producer Peter Lenkov. “Now the Hawaii Five-0 viewers will actually get the chance to tell us who they think committed the crime and we will listen. I love that our dedicated and attentive fans will actually play a part in resolving our story.”

Sounds fun, huh? The special episode titled “Kapu” (translation: “Forbidden”) airs this Monday night (1/14) at 10PM. Watch a trailer after the break.
