‘Hawaii Five-0’ Season 9 Premiere Spoilers: Synopsis, Episode 1 Trailer Released

It’s time to see what Commander Steve McGarrett (Alex O’Loughlin), Detective Danny Williams (Scott Caan) and the rest of the “Hawaii Five-0” task force is up to when the CBS returns on Friday. When Season 9 premieres, it might seem a bit familiar to fans of the 1968 version of the show.

Titled “Ka ʻōwili ʻōka'i (Cocoon),” Friday’s episode is actually a retelling of the first episode of the original series, which was also called “Cocoon.” The old version of it followed McGarrett (Jack Lord) as he looked into the death of a friend after he realized that the guy didn’t drown like people originally thought. It turned out that Chinese agent Wo Fat (Khigh Dhiegh) was involved, and McGarrett worked to take him down.

Fans of the rebooted series are very familiar with Mark Dacascos’ take on Wo Fat, and they’ll become even more familiar with him as he returns for episode 1 of Season 9. Making this “Hawaii Five-0” broadcast extra special is that the late Leonard Freeman, who created the original show and wrote its pilot episode, is credited as a co-writer of this retelling. Joining him as the other co-writer is executive producer Peter M. Lenkov.

“After Steve’s CIA agent friend is killed, McGarrett lets himself be captured by the group he thinks is responsible and endures a torturous sensory deprivation tank to find the killer,” the Season 9 premiere synopsis reveals. “Also, Tani [Meaghan Rath] wrestles with whether or not she will tell McGarrett about the murder weapon she found at Adam’s [Ian Anthony Dale] house.”

To recap, in the “Hawaii Five-0” Season 8 finale, titled “Waiho Wale Kahiko (Ancients Exposed),” Tani found a gun in a drawer at Adam’s house and she believes it might’ve been the weapon used to kill his sister. This put her in a difficult position of having to decide who to tell and what to do about, which is something she’ll still be dealing with at the start of the new season.

As for Steve and Danny, they continued to work on their restaurant, but they realized that they needed more financial help to make it work. That’s where Kamekona (Taylor Wily) came in. He agreed to a contract with the cops to join them as a silent partner, but because he’s Kamekona, he doesn’t plan on being too silent.

Find out what’s next for everyone when “Hawaii Five-0” Season 9 premieres on CBS on Friday at 9 p.m. EDT.
