|Po'ipu (The Siege)|
|Season 1, Episode 9|
|Air date||November 15, 2010|
A guard attached to an upcoming security detail is murdered before he can outline the details of an assassination plot against a ruthless general who's planning on attending an Aid Summit. Five-0 must protect the general and the general's family while investigating the murder, only for Steve to discover one of his former SEAL buddies is the true mastermind behind the attacks.
Erica Raines seduces a male security guard, David Atwater before leading him to a hotel room where she strangles him to death before gathering up her things and leaving while also placing a "Do Not Disturb" sign on the door.
As such, the Hawaii Five-0 Task Force led by Steve McGarrett is assigned the case given how the death may be connected to an upcoming Aid Summit concerning General Pak, a mass-murdering military general from Sandimar.
As the investigation progresses, the team find and confront Raines but when she tries to flee, she is struck by a bus and dies instantly from her injuries.
Steve later learns that Taylor and Raines were working together so that they could kill Pak. As they all hide in the McGarrett home, Pak reveals that he's there solely to seek political asylum and confess his crimes.
Taylor and his team arrive and begin assaulting the house with Danny Williams, Chin Ho Kelly and Kono Kalakaua fending off the attackers and protecting Pak and his family while Steve and Taylor engage in hand-to-hand combat on the beach.
Just when Taylor gets the edge, Steve manages to shoot Taylor fatally, ending the battle and solving the case.
The next day, Steve and Danny watch as Pak and his family depart.
Steve McGarrett: Let me ask you a question. Where do people from New Jersey vacation?
Danny Williams: Um, I don't know. I-I would imagine they vacation all over the place.
Steve McGarrett: Okay. And you're a-you're aware of the fact that, perhaps, many people from New Jersey vacation here, in Hawaii?
Danny Williams: I'm sure some misguided people do, sure.
Steve McGarrett: Okay, good. And how many Hawaiians do you think vacation in New Jersey?
Danny Williams: (exasperated) I don't know.
Steve McGarrett: I can help you with that answer, if you want. The answer is zero, Danny. Because nobody here, except you, wants to be there. Okay?
Nick Taylor: She's a mechanic, and a very good one.
Kono Kalakaua: A mechanic?
Nick Taylor: An assassin.
Nick Taylor: I killed for God and country for years. But I figured it was about time I got paid for it. Five million dollars to keep Pak from testifying, and I'll cut you in, Steve. All you got to do is put a bullet in him.
Steve McGarrett: You know what? I'll put a bullet in you first. How's that?
Nick Taylor: Oh, I'm glad to see civilian life hasn't dulled your sense of humour.
