Gibbs and the team investigate when a 6-year-old boy informs NCIS his father has been kidnapped. Gibbs quickly develops a unique bond with the young boy whose missing father is a Lt. Commander working as the Navy's liaison with a defense contractor on a highly confidential project called Honor. The NCIS team discovers that the top-secret program, for which the missing Commander holds the only code, has been hacked and classified data has been removed. As the evidence begins to indicate the kidnapping may be a hoax, Gibbs holds his ground when his gut tells him the Lt. Commander is innocent.
