The NCIS team is called in to investigate when the decomposed body of a woman in a wedding dress is found in a cell beneath abandoned military housing.

As Gibbs and his team investigate the bizarre discovery of the woman in a subterranean prison cell made to resemble a 1950's bedroom, the evidence indicates that she had been imprisoned for months and died when her air supply was cut off. Subsequent evidence indicates that this murder may be only one in a pattern of similar incidents and Gibbs and the team find themselves racing to find another possible victim who disappeared from a Navy base in Florida.
