McGarrett's friend and mentor Joe White asks McGarrett to investigate the death of SEAL team member, Max Garcia who apparently committed suicide. McGarrett persuades Max to redo the autopsy (Max's boss did the original), and Max discovers that Garcia was murdered and now Five-0 (including Lori Wilson) can officially investigate. Joe helps the team by getting whatever information he can from the military and when a second SEAL from the same team is found murdered; McGarrett realizes they're being targeted. They work to find the killer and the motive for these murders in order to save the rest of the team and McGarrett manages to rescue the final team member unaccounted for in a daring sky dive maneuver. Chin Ho worries when he learns that Kono is hanging out with a bunch of dirty ex-cops ever since she was kicked off the force.
