Hawaii Five-0 is an American police procedural drama television series and a re-imagining of the original 1968–80 television series. The series is produced by K/O Paper Products and 101st Street Television in association with CBS Productions. The title of the new show uses a zero in place of the letter "O" in the original title.
Hawaii Five-0 debuted on CBS, the same network that aired the original version. Like the original version, it follows an elite state police unit/task force set up to fight crime in the state of Hawaii. It premiered on Monday, September 20, 2010, 42 years to the day from the premiere of the original show, September 20, 1968. On October 21, 2010, CBS announced that Hawaii Five-0 had been given a full season order of 24 episodes.
On March 14, 2012, CBS renewed Hawaii Five-0 for a third season, scheduled to premiere on September 24.
The series covers the actions of a small special state task force created by the Governor of Hawaii, Gov. Pat Jameson, to investigate serious crimes throughout the Islands, as Hawaii does not have a conventional state police force. The team is headed by Lieutenant Commander Steve McGarrett, USNR as it investigates crimes ranging from terrorism to kidnapping. McGarrett chooses as his partner Honolulu PD Detective Danny "Danno" Williams. He fills out the team by selecting Chin Ho Kelly, and Chin's cousin, a rookie HPD cop named Kono Kalakaua. The task force does not follow the normal chain of command and instead reports directly to the Governor's office. One unexplained part of the story concerns the name Five-0. Taken from a shirt worn by the young Steve McGarrett in a video that the team watches, Kono decides that Five-0 would be a good name for their task force. However, it is not explained how everyone (including tourists) seems to know what Five-0 is despite it being an unofficial name coined in a private meeting, although the name appears to have been made official in later episodes. Five-0's headquarters are apparently located in Aliiolani Hale, site of a famous Kamehameha Statue, which features prominently in the series; in real life Aliiolani Hale serves as the central headquarters of the Hawai'i State Judiciary and where the Supreme Court of Hawaii regularly convenes.
Each episode typically begins with a crime being committed or a body being discovered (although in one episode the team was assigned to provide protection for a foreign dignitary), and assignment of the subsequent criminal investigation to the unit by either the governor herself or her representative. The task force uses the authority of the governor's office to gain access to crime scenes and investigations involving the Honolulu Police Department (HPD) when they cross paths. To assist them in their investigations, the team is granted immunity from prosecution for actions committed in the line of duty, although this immunity is revoked by the lieutenant governor following the governor's assassination.
A major character arc set up in the pilot episode revolves around the murder of McGarrett's father, who was working on a corruption case even after retiring from the HPD. After the terrorist responsible for his father's murder is apprehended, a mysterious figure interrogates him about Steve's investigation into his father's old cases. This figure is later revealed to be Wo Fat, a criminal with ties to the Japanese Yakuza, and is possibly connected to the suspected car-bomb murder of Steve's mother (a death originally ruled an accident). When his father investigated this as the head of the HPD Organized Crime Task Force, he began to dig too far into the corruption, forcing him to lay off the investigation. He nonetheless saved all his evidence in a toolbox, all of which was left to his son in the hope that he would someday conclude his father's work.
