In the Season 8 premiere, McGarrett and Danny recruit Tani Rey (Meaghan Rath) to join the task force when diabolical hacker Aaron Wright (Joey Lawrence) releases a dangerous arsonist from prison.
The season premiere includes animation of one of McGarrett and Danny's infamous "car-guements." Also, Randy Couture returns, and Joey Lawrence joins his brother, Andrew, when he guest stars as Aaron Wright, a hacker.
Ian Anthony Dale, Meaghan Rath and Beulah Koale join the cast this season. Dale has recurred as Adam Noshimuri since Season 2, becoming a trusted confidante and resource for the team who will now be recruited by McGarrett to work for Five-0.
Rath plays Tani Rey, who McGarrett (Alex O'Loughlin) recruits after finding her working as a lifeguard at a hotel pool after she was kicked out of the Police Academy, despite being a first-rate candidate.
Koale portrays Junior Reigns, a former Navy SEAL who just returned from serving his country and asks McGarrett, a fellow SEAL, for a job, hoping to repurpose his skills as a member of Five-0.
Season 8 also stars Alex O'Loughlin, Scott Caan, Chi McBride, Jorge Garcia, Taylor Wily, Kimee Balmilero and Dennis Chun.
Hawaii Five-0 is produced by CBS Television Studios. Peter Lenkov, Alex Kurtzman, Roberto Orci and Eric Guggenheim are the executive producers.
