Last Updated: Oct 10, 2021

Network: CBS

Detective Steve McGarrett, a decorated Naval officer turned cop, returned to Oahu after Hawaii's former governor persuaded him to head up the new team: his rules, no red tape and full blanket authority to hunt down the biggest "game" in town. Joining McGarrett are Detective Danny "Danno" Williams, a relocated ex-New Jersey cop; Captain Lou Grover, who formerly headed Hawaii's SWAT unit; Jerry Ortega, the islands' local conspiracy theorist; and Tani Rey, a bold, recent police academy graduate. Helping them is Adam Noshimuri, a friend with old ties to a deadly crime family; Junior Reigns, a former SEAL; Kamekona, a local entrepreneur who has his pulse on the Island; Sgt. Duke Lukela, a trusted member of the HPD; and medical examiner Dr. Noelani Cunha. The state's brash Five-0 unit, who may spar and jest among themselves, remain determined to eliminate the seedy elements from the 50th state.
