'Hawaii Five-0' season 7 episode 6 spoilers: Kono and Adam abducted; Steve and Danny investigate medium's death

As per tradition, "Hawaii Five-0" will be getting into the spirit of Halloween in this week's episode, and it looks like the celebrations will be cutting Adam (Ian Anthony Dale) and Kono's (Grace Park) reconciliation short.

In the episode titled "Ka Hale Ho'Okauweli," which translates to "House of Horrors," the newly reunited husband and wife will be the victim of what looks to be a death cult wearing identical white masks reminiscent of the "Scream" and "Halloween" movies. What could their intentions be?

The episode preview shows the two of them chained on separate posts with other victims of the cult. In another scene, Kono and Adam along with at least two other girls are shown being led into the woods by a cheering crowd of masked men who seem to be gearing up for a deadly Halloween night hunt with their helpless prey.

Do these people know that they've just kidnapped one of the members of Hawaii's elite Five-0 Task Force and her equally skillful husband? Will Kono and Adam be able to fend for themselves and for the other victims, or will their team figure out that they're in trouble soon enough to rush to their aid?

The official synopsis for the episode also states that the rest of the Five-0 team will be caught up in a case of their own when a spirit medium with a questionable past is found dead. Further investigation reveals that the medium died from an intense bout of fear allegedly brought on by a poltergeist.

What other secrets will the Five-0 uncover as they look further into the life of a spirit medium? Which side will Steve (Alex O'Loughlin) and Danny (Scott Caan) take when they have one of their usual arguments? Who believes in the supernatural and who does not?

A staple of every Halloween episode of "Hawaii Five-0" is Dr. Bergman's (Masi Oka) annual Keanu Reeves-inspired costumes. Will Five-0's chief medical examiner finally be back in this week's episode to sport yet another Keanu movie character that never fails to drive Danny insane?

"Hawaii Five-0" season 7 episode 6 airs on Friday, Oct. 28, at 9 p.m. EDT on CBS.
