The upcoming episode will see Steve McGarrett (Alex O'Loughlin) and his team face a possible terrorist attack in Oahu, which means they will need to do what they can not only to identify the people behind this, but also to prevent this from happening altogether.

According to the episode synopsis, the tip is anonymous, so viewers will have to stay tuned to see if the call that the lieutenant commander receives is the real deal. Nonetheless, CarterMatt theorizes that the show will be action-packed, especially given that the season is due to end the following episode, so it is likely that viewers will be at the edge of their seats all throughout this episode.

Meanwhile, Chin Ho Kelly (Daniel Dae Kim) and Abby Dunn (Julie Benz) will find themselves face a turning point in their relationship. They will need to make a difficult decision that could dictate where their pairing will go. This episode will feature the return of Benz on the show, as the actress was also busy shooting "Training Day." Given her busy schedule, however, their breakup is as likely as them officially getting together on the show.

According to Spoilers Guide, the guest stars for the episode include Taylor Wily as Kamekona, Ian Anthony Dale as Adam Noshimuri, Omid Abtahi as Naser Salaam, Willie Garson as Gerard Hirsch, Ingo Rademacher as Robert Coughlin, Nick Shakoour as Adnan Khalid, and Leon Williams as Kalea.

The episode is titled "He Ke'u Na Ka 'Alae a Hina," which is roughly translated to "A Croaking by Hina's Mudhen," according to Christian Post. Episode 24 of season 7 of "Hawaii Five-0" will air on May 5, Friday, at 9 pm on CBS. Meanwhile, the show's season finale will air on May 12. The episode's title is "Ua Mau ke Ea O ka Āina i ka Pono," or The Life of the Land Is Perpetuated in Righteousness." It is rumored that this episode will feature Steve risking his life.
