Five-0 investigate when the body of a dead salvage diver is discovered and they soon discover that the victim was looking for more than sunken treasure.
Blake Spencer, a diver is found dead at sea and Hawaii Five-0 discover that he'd discovered treasure from a sunken galleon off the Oahu coast with Lieutenant Commander Steve McGarrett and Detective Danny Williams learning that the treasure is fake.
When they discover Spencer's boat, Steve and Joe White drive, finding an ambulance that sank in 1939 which houses the remains of Spencer's grandfather and Sylvia Spencer's father, Robert S. Murphy with Spencer wanting to do that so that he could give his mother who is suffering from Alzheimer's disease closure.
The team soon learn that the murderer is Jimmy Koller who worked with Blake and who killed Blake, believing that Blake wanted for the treasure for himself with Koller believing that the story that Blake told him about his grandfather being in the sea to be nothing more than a lie although Lori corrects Koller on that.
Meanwhile, Chin realizes that Kono logged onto the HPD Database using his password while Steve realizes White did not release the video with Wo Fat and his father to the Department of Defense with White claiming he was trying to protect John.
- Patty Duke who plays Sylvia Spencer is credited as a Special Guest Star.
