It's been awhile, but Hawaii Five-O returns with a new episode next week and will waste no time getting to the heart of one of the show's central storylines: tracking down the Yakuza who had his McGarrett's parents killed.

Viewers will be introduced to Larisa Oleynik as a CIA agent who claims she can help with this mission, while the team also searches a convention scene in search of a murderer.

Check out the official promo below for "Na Me'e Laua Na Paio" and prepare to ogle some seriously hot beach bodies again on Monday night...
