Nuclear weapons in Waikiki and blissful nuptials don’t mix well, so the “Hawaii Five-O” team has to take on a case, even on the day of Kono’s (Grace Park) long-awaited wedding in the May 8 25th episode and Season 5 finale, “A Make Kaua” (Until We Die). The love Steve (Alex O’Loughlin) can’t leave behind returns to the island, but preventing mass casualties takes precedence over all the catching up with words never said that they have to do. Chin (Daniel Dae Kim) confronts Adam (Ian Anthony Dale) over the company he keeps in those photos shared by Gabriel Waincroft (Christopher Sean), but ends the day with bigger problems, and Dr. Bergman (Masi Oka) ponders over his wardrobe statement!
Under cover of darkness, a convoy of nuclear weapons is accosted, and a single warhead out of six is taken, and a pilot is ordered to divert to Hawaii in a “change of flight plan.” Adam comes home to find Chin waiting, instead of his almost-bride. He has no interest in wedding chit chat, he wants answers about the photos from Waincroft. This isn’t the first time that Adam has been in this rodeo over compromising pictures. Accustomed to beginning with “It’s not what you think,” he calmly describes how he was trying to negotiate a buyout from Yakuza, from crime boss, Shiomo. The only option presented to Adam was to leave with nothing, and he chose that option, leaving him with his personal honor, and the love of his life, Kono.
Captain Grover (Chi McBride) and the team watch Waincroft on surveillance, and beyond the warhead issue, Lou puts out that this means the criminal nemesis “is back in business” and taking care of competitors. Steve sees what he thinks is a dream vision of Catherine after finishing a morning swim, but it is her in the flesh, asking, “You looking for this?” holding up his shirt. As always happens in the battle against the underworld, the case call comes in, and Steve pleads, “Don’t go anywhere,” answering his call of duty. It feels just like old times. Max’s examination reveals that the pilot was shot on landing, and Lou orders everyone way from the plane with “Nukes!” The weapons have been traced from a North Dakota base. It may be good news that only one warhead was taken, but that means that the intent is not to sell, but to destroy lives. Danny and Steve have another discussion on matters of the heart, and Steve says he will adopt Danny’s approach, and talk to Catherine “when the time is right,” after failing Danny’s test of 20 questions! Investigation reveals that a spurned a military man, Josh Bennett (Jeffrey Nording) is a main prospect for selling the weapon to a terrorist, Omar Sadak (Ken Davitan). He has held a grudge for 14 years.
A snagged suspect turns out not to be too fond of confinement, but shots start fire from everywhere around the shipment containers, and Bennett tells McGarrett that the contact are looking for is long gone. The day of the wedding is still filled with talk of the case. Catherine is a knockout in royal blue, and when Steve inquires “How long can you stay?,” her reply is “How long do you want me to stay?” The door is certainly open for renewal of long-term romance. The terrorist’s body is washed up dead on the beach, and Max says this time of death was even before Bennett was in custody. Steve employs some personal ammunition of his own to draw out an admission from Bennett that “bombs will be dropping everywhere” soon, and this time, there will be no stopping “until it’s a parking lot” in the Arab countries. Chin is tagging a trolley driver in Waikiki, where 100,000 lives are at risk of being lost. Danny and Steve arrive to find the driver dead, and the nuclear device with its clock running, and the means to stop it disabled. This bomb on board is about to blow.
Jerry (Jorge Garcia) and Max are jazzed to be sharing Table 13 at the wedding, and Max does indeed make a bold black and white ensemble statement, ala Tony Manero. Adam relays a message from Kono that her ceremony will be delayed by an important, but unavoidable incident, and instructs the guests to wait. What the guests don’t know is that Steve and Danny are racing against the clock in Kamekona’s chopper to dispose of the ticking weapon far out at sea, then hoping to dodge the impact and survive to see the wedding. The mission will take all of two minutes! Danny and Steve have some heated chopper convo, too, and Steve assures “you’ve got two kids now Danny, and you’re not going to die today!” Danny manages to ditch the heavy weapon from the chopper, and Steve’s evasive skills get them out of the back draft. They arrive on the wedding grounds, suits and ties intact, and boss, Lou, gives the exclamation “James Bond, my ass!” Catherine and Kono offer warm hugs, as Danny adds, “Good to see you, Catherine.” Kono needs no more than 5 minutes to fabulous, looking like a vision from heaven in her wedding gown, as Danny’s daughter, Grace, looks glorious in pink. When Kono asks her cousin about the rings, he remembers that they are in the car. When he sees they have been taken from his glovebox, he startles, and Waincroft is pointing a gun straight for his head, saying , the time has come to “repay the debt.” The ultimate criminal tells Chin that he will always be thought of as “a dirty cop,” and offers him a “50-50 partnership.” That not being an option, he orders Chin to turn around, and Chin reminds him of cowardice of shooting someone in the back. “You’re not the first Kelly I’ve killed,” Waincroft responds. For a moment, the scene switches to an anxious, waiting bride, as Chin turns to find no one there. Will there be a wedding, and who will live to see it?
