The Five-0 Task Force investigates the murder of an O’ahu Sate University professor in a special episode that allows viewers to choose the ending of the episode and the identity of the killer. While investigating the case Danny (Scott Caan) is forced to drag around his deadbeat nephew Eric (Andrew Lawrence) from Jersey sent to the islands his sister who hopes Danny can knock some sense into him before he completely flushes his life away.
After talking with one the professor’s female students (Janel Parrish), Five-O discovers the man had begun an investigation into cheating in his classroom shortly before his death. From his recent odd hours and erratic behavior they also discover the teacher was working on a secret project involving an extinct plant species. To discover more McGarrett (Alex O’Loughlin) and Chin-Ho (Daniel Dae Kim) take a trip to the northern-most private island where the professor had taken several hunting trips in the months before his death.
In the episode’s B-story Kono (Grace Park) babysits Sang Min (Will Yun Lee) who has been transported back to the islands to testify in a case in exchange for a sentence reduction. Aside from his annoying personality, Kono is also troubled with his nochalant attitude including talking with Kamekona (Taylor Wily) from prison about his trip. Despite Sang giving the protective detail the slip to check in on his wife and son, Kono makes a connection with the convict and agrees to try and help him return to the islands to be closer to his family if he so desires.
The episode hides the real motive for the murder, the potentially priceless cure the man had discovered while working with a botanist (Jeff Fahey), until the end of the show leaving several possibilities for the fans to choose the real killer. The choice of killer we’re given isn’t all that interesting, but it does provide a action-packed final few minutes through the jungles of the northern island. The alternative endings (which you can view online) vary by only the smallest degree as the events unfold the exact same way with only the players being different. In the end, the episode works better than the gimmick.
