Hawaii Five-0 is a remake of a classic TV show, which is based around detectives and police officers in Hawaii.
Stars Alex O'Loughlin as Steve McGarrett, Scott Caan as Danny "Danno" Williams, Grace Park as Kono Kalakaua, Daniel Dae Kim as Chin Ho Kelly more recently added Lost alum Jorge Garcia as Jerry Ortega.
The series has both cases of the week and long-term arcs, one of which was explained heavily in the highly anticipated and surprising anniversary celebrated with a special 100th episode with exciting reveals surrounding Wo Fat.
The relationship between McGarrett and Danny is part of the fun of Hawaii Five-0, as the two rib each other constantly. Before coming to Hawaii, Danny was a big city type of guy, and he has had a very difficult time adjusting to beautiful island life. Sure, it seems crazy to you and me, but for him it's a thing.
Kono and Chin Ho are cousins, with Kono joining Five-0 because of some special abilities she showed on an early case.
Other than great stories, you will surely be wowed by the shirtless Alex O'Laughlin scenes. What good is an incredibly handsome man in Hawaii if he doesn't get in the water once in a while?
