Zack Slater, a teenage expert computer hacker is released from juvie but is abducted shortly after and later found dead in a van by members of the Hawaii Five-0 team who have been called in to help in regards into Zack's kidnapping.
As Officer Kono Kalakaua searches Zack's room, a mercenary team led by South African mercenary Sean Winston arrive, taking everyone hostage.
Kono offers to give the team the password but only if the team let everyone else go.
The mercenaries relent and escape in a truck that H50 provided although it's later revealed to be a trap.
Inside the truck, Kono successfully overpowers Winston while Danny, Steve, and Chin take down the rest of the team, arresting them.
Steve later reveals to Kono that Zach had gained information on a mobster, Richard DeSalvo that Winston and his group had helped escape protective custody three years previously.
Steve and Chin eventually track down DeSalvo and arrest him while Kono subsequently informs Zach's family what he did which leaves them relieved and comforted although they're still grieving over their son's murder.
Meanwhile, Steve's sister, Mary McGarrett returns for a visit, now a caregiver with a boyfriend, Morty Sapperstein in tow but is unrelenting in not wanting to see her mother.
Her boyfriend however, convinces her to see Doris, reciting his story when his estranged daughter was killed years before by a drunk driver from Oakland who had fallen asleep at the wheel.
A while later, Mary and Doris share an emotional hug as Steve looks on.
