Last time on episode 9, Five-0 investigated the murder of a college professor where Detective Chin Ho Kelly and his nephew, Eric, went under cover in a university to solve the case. The two portray themselves as the new professor and student, so that they could question the college students and find out what exactly happened.

The episode titled "Hana Keaka" (Charade) also showed Chin bonding with Agent Dunn during her stay in Hawaii.

This week's episode 10 is expected to be an explosive one, with a lot of things that are going to get down, before the show hits mid-season hiatus. Catch the Five-0 team solve the murder case of a promising local boxer as the season's biggest villain Gabriel aka Gabe makes a comeback.
