The Immortals

The discovery of a drowned sailor in dress whites, with an officer's ceremonial sword and weights chained to his waist, sparks a suicide investigation and eventually sends the team to the USS Foster so that they can dig into the deceased officer's life and find out what his colleagues thought of him. Kate refuses to believe that the deceased sailor committed suicide as, like her, he came from a Catholic family where suicide is a mortal sin. Meanwhile Abby discovers a link between the crew of the USS Foster and an MMORPG known as 'The Immortals', and begins searching the game for clues and evidence in order to assist Gibbs in solving the case and saving the ship from possible destruction.
