The series premiere opened in Pohang South Korea, where a military transport headed out from a military base. Commander Steve McGarrett cell phone rings and the prisoner Aton told him he should get it. On the phone was Aton’s brother, Victor who had McGarrett father at gun point in Hawaii. 

Victor kept McGarrett on the phone to triangulate their location. In the ensuing fire fight most of the soldiers and Anton was killed. In retaliation Victor killed McGarrett’s father.

McGarrett landed in Hawaii for his father’s funeral and met with the Governor who offered him the lead on a task force to stop men like Victor Hesse. McGarrett initially turned her down but after running into resistance at his father’s house in the form of Detective Danny Williams, he took the job.

McGarrett took over the investigation and recruited Danny Williams on to his team. The two of them went to question the man who may have sold Victor Hesse the gun that MacGarrett’s father was shot with. However, things did not go well and the suspect was killed. In his house they found a young asian girl tied up.

Steve and Danny went to see an old friend Chin Ho Kelly who was a Detective and is now a security guard. Steve told Chin that he needed him and it would get him back on the force. With Chin’s help they found they needed to trap a man name Sang Min. To do this they recruited Chin’s cousin Kona who is graduating from the Police Academy.

Kona helped catch Sang and he gave up Victor’s location. Steve and Danny went to the ship that Victor was on and was able to stop the ship and in the shoot out Victor was shot by Steve and fell in the water. The team met at their new headquarters afterwards where they started discussing picking a name for the team.
