As celebrities get older, they often tend to shave a year or two off their birthdays. Not so with New Orleans. NOLA is going to be 300 next year, and NCIS: NEW ORLEANS is ready to party. But before they can get the party started, Petty Officer Michael Thompson (guest star Onye Eme-Akwari) is beaten and murdered, shot in the head, execution-style. When Thompson’s body is found on a park bench, a lead points law enforcement to a group of homeless children.
