The team and Coast Guard Investigative Service join forces when a Navy diver seeking sunken treasure is murdered. Both teams suspect a wealthy doctor who was funding the treasure hunting expedition is the culprit, but the evidence just doesn't add up. Eventually, they figure out that the diver was scamming the doctor, fooling him into withdrawing cash from his accounts to find a nonexistent treasure. The diver killed the doctor and faked his own death using the body. Both the NCIS and CGIS teams apprehend the diver and the doctor's wife, who was his accomplice.
