A Navy petty officer, Jerry, who's the only witness in a civilian capital-murder trial, receives and plays an eerie DVD, then he disappears; a commonwealth attorney (a prosecutor in Virginia), Gail, seeks help from Gibbs; the gang investigate, and they find a turkey. Tony behaves differently, and Gail shows interest in Gibbs; Duck and Abby tell about the bird. Gibbs and Ziva find Jerry, who suggests a new twist. Gibbs persists, then he receives a visit; McGee and Ziva see a guy on a street, then Gibbs and Tony chat with the guy, who describes a strange deal. Jerry's mouthy comments annoy many people. Gibbs and Gail oppose each other on several points. Another man dies. Duckman receives several distracting e-mail messages. The team learn about the various facets of this case and figure them out, then all the loose ends work out. Tony reverts to his previous behavior.
