This time, Steve and Danno take some time out to go on a hike in scenic Hawaii where Steve’s Dad used to take him. They talk quite a bit about Steve’s Dad, Wo Fat, and the evidence of this bizarre case from the past. While they are there Steve repels down a cliff and finds a dead man, shot through the head and likely dumped there via plane or helicopter. Steve starts to climb back up the cliff but a rock falls loose and clocks him on the head throwing him backwards, breaking his line, and sending him crashing down to hard rock. Steve breaks his arm and cannot climb back up so Danno hikes out to get cell reception and call for a medevac team.
Danno, Chin Ho, and Kono are left to investigate the killing while Steve is getting patched up. The body is that of a local fisherman who had an altercation just a few days prior to his murder. They find the fisherman he had a beef with and find meth on his boat. They guy tells the 5-0 team that he tried to persuade the victim into helping move the drugs but he refused and was left alive. Chin Ho uses the fish scales evidence they found to track down the fish sold by the victim that day. Danno examines the fish and finds one has a bullet hole in it and they recover the bullet.
They also discover that the victim was moonlighting at a jet charter company as a fuel man. Steve puts some details together and suspects that the victim may have seen a man named Rutherford helping his son escape prosecution for strangling his 19 year old girlfriend. To eliminate the only witness he follows the fisherman home and kills him on his boat and then uses a chartered flight to dump the body. The 5-0 team closes in and wraps the case.
In a side story we learn who it was that stole the money Chin Ho was accused of taking and why he is not interested in setting the record straight since he now feels at home with the 5-0 team. Good stuff!
