When a young, wealthy couple are found murdered in their home, the team enlist the help of a conspiracy theorist who is also an old school friend of Chin's to help them solve the two killings while Catherine prepares to retire from the Navy for good.
Married couple Kaylea and Phillip Van Horn are found murdered in their swimming pool, and evidence points towards a professional hit. They later find that one of their artifacts, an emblem of the Royal League, a disbanded secret society, of which Phillip's great-great grandfather was a member, is missing.
The team turns to Jerry Ortega, an old friend of Chin Ho and a conspiracy theorist. He suggests that the killers wanted the emblem as "the key" to find rings smuggled from Italy that are hidden in Hawaii. Jerry later believes they are hidden in one of the Kamehameha Statues.
Further investigation turns to Ellis Gregory, a mercenary whose team paid Phillip's brother for access to his house.
One of the statues is discovered to have been replaced with a look-alike. After the mercenaries are found in a museum to recover a key, Five-0 arrive and arrest them. Later, the rings are indeed found under the foot of the recovered statue.
The team later celebrate Catherine's retirement.
