"NCIS" and "NCIS: New Orleans" will have a crossover episode and it is definitely worth watching! The next Tuesday will be a huge night for fans out there who both enjoy the two editions. Normally, fans are treated to one big crossover event in a year and this one will be featuring action-packed plot with the undercover mission like no other. The new characters of the show will be instrumental to the outcome of the episode. Previous crossovers do not feature these new characters so this episode will have a very different approach.

"NCIS" - "NCIS: New Orleans" Crossover Episode promo has already been released. Certainly, Nick Torres (Wilmer Valderrama) will be the one spending his time doing undercover work in New Orleans. The crossover is not an episode where all the actors will be present on both shows, appearing in the two-hour episode. There will be a focus and a tad bit concentrated. However, the story surely carries over from the first episode to the next.

With regard to the story, it will be centering on a terror playbook, which can provide valuable government information to organizations wanting to destroy the country. If the said book fell into the hands of the bad guys, World War III will be in sight. Therefore, it is very important that many characters will be involved to find the playbook when it was stolen.

One surprising thing about the crossover episode is that CBS seems not interested into swapping "NCIS: New Orleans" and "Bull" for this night. Therefore, "Bull" will be the breather show between the two. This is funky since "NCIS: New Orleans" are headed down in the rating game and this might be the way for devoted backs to return to watching the show again.
