Five-0 investigates the murder of a Lua (ancient Hawaiian hand-to-hand combat) master and McGarrett hires a private investigator to follow his mother.
Thomas Hoapili, a businessman and cousin of Kamekona Tupuola is found dead in the trunk of a car.
Steve McGarrett and Danny Williams of the Hawaii Five-0 Task Force, believing Kamekona is out to avenge his cousin trail Kamekona and arrest him although it's later revealed that Kamekona's target was not involved in the killing.
The team go through video footage and discover that Hoapili was kidnapped and unwillingly fought in a top-secret underground fight club and received such extensive injuries that Hoapili would not have survived.
The clubs are full of numerous spectators who pay huge sums of money and the club is led by mixed martial artist Ramsey Pollack who is wanted in connection with similar murders.
Hoapili's daughter, Maggie reveals that her father was a master at Kapu Kuialua, a martial art, and she too practices.
Maggie is later kidnapped also to compete.
Five-0 eventually locate the fight club and rescue her before she can be killed by the man running it while Steve taunts the main man intending to kill Maggie.
Meanwhile, Steve hires Mick Logan, a private investigator to keep tabs on his mother's whereabouts, which eventually leads the two to start a relationship after Doris knows he was hired by her son.
Danny Williams: You hired somebody to run surveillance on your mother?
Steve McGarrett: Okay, I know what you're gonna say.
Danny Williams: Well, what am I gonna say?
Steve McGarrett: That hiring somebody to spy on their mother is the act of a crazy person.
Danny Williams: Uh, yeah, I would've used different words like, uh, whack job or psychopath. Crazy works, though. It works.
- It's revealed that Kamekona's full name is Kamekona Tupuola.
- The first rule of 1999's film Fight Club is mentioned "You do not talk about Fight Club"
- When Steve jumps into the empty pool, he tells Shane if he wants to hit someone come hit him. Shane takes out a knife swinging it in large circles before Steve shoots him in the knee. This is reminiscent of the famous scene with Indiana Jones in Steven Spielberg's 1981 film Raiders of the Lost Ark.
