For every episode of "Hawaii Five-0" that airs without the season's big-bad, fans get a little anxious to see how things are going to end up for Adam and his new wife Kono. That did happen in the last episode, but this Friday fans will get another case of the week.

Episode 9, titled "Hana Keaka," which translates to "Charade" will air on broadcast network CBS next Friday, Nov. 20 at 9 p.m. EST, according to TV Guide.

What fans of the show will get on the next episode is something that is a little unexpected for Danny (Scott Caan), who will get to go undercover on the task force in a role that he does not quite fit to a tee.

According to Spoilers Guide, a professor at a college will be killed and the unit is clueless as to who would want him dead. Of course some of the likely suspects would be students who don't like his style, but apparently none of them have even met their professor yet.

That's why Danny will be going in as his replacement on an undercover assignment to help flush out the perp or find any clues that may lead them to the killer.

The season has been taking many twists and turns with their cases of the week, which feature a little of the season-long storylines mixed in with daily cases that seem to be just getting in the way here lately.

According to Entertainment Weekly, the last episode was about a series of long cons that had the ultimate objective of uploading a virus to the Five-0 computer system. That was spearheaded by Adam and one of his con-cronies, but the plan is about to backfire on him once the unit sets their alternative plans into motion.

Fans can watch a preview below for the next episode.
