Five-0 dives into the world of North Shore surfing when the CEO of a successful company is murdered while Kono also revisits her past.
Various people including Officer Kono Kalakaua are at a surfing competition with everyone witnessing the murder of Kono's mentor, Ian Adams.
As such, Kono's colleagues from the Hawaii Five-0 Task Force, Lieutenant Commander Steve McGarret and Detective Danny Williams arrive to investigate the crime with Lieutenant Chin Ho Kelly, Kono's cousin telling them about the competition and about how Ian was the one who paid for Kono's rehab and recovery when she blew out her knee during a surfing competition.
Despite Steve urging Kono to take some time off so that she can grieve for her mentor, Kono refuses, instead choosing to help them out on the case.
As the team pursue other lines, Kono meets Ben Bass, her ex-boyfriend and the two reconnect.
Although Levi and Diego are cleared, they're soon exposed as the ones who attacked the camp that Kono and Ben were at with Levi and Diego being arrested again.
Hawaii Five-0 eventually learn that it was Randall Barrett who fired the shot that killed Ian Adams and as soon as they've arrested Barrett, they also arrest Carlton Bass, Ben's stepfather.
