In episode 13, the NCIS team worked on a murder mystery of a Navy Lieutenant who was found dead near a garbage truck with a tracking device implanted in her body. The related evidence hints at an old human trafficking ring that the team assumed was not functioning anymore.

Moving on to episode 14 of "NCIS" Season 13. Even though the upcoming segment is seven days away from its airdate, the network has already released a synopsis for it. According to Spoiler TV's press release for "Decompressed," the agents of Naval Criminal Investigative Services will carry out an unconventional investigation in the upcoming instalment.

A deep sea diver is found dead. In the unusual investigation, the NCIS team must look underwater for evidence as the murder took place when the diver was on duty. The murder has been committed from outside a high-tech decompression diver tank.

As NCIS begins the investigation, the body of the deceased sea diver and the suspected co-workers are forced to stay in the diving chamber for four days. Meanwhile, the team attempts to complete the investigation from outside the chambers.

The network is yet to release a promo video for "NCIS" Season 13 episode 14. However, Spoiler TV has published some promotional photos giving a glimpse of the upcoming instalment "Decompressed.

In addition, fans can expect to see some progress in Ellie Bishop's (Emily Wickersham) storyline. The NCIS agent is going through a divorce and it will impact her professional life in a big way.

In an interview with TV Guide, Wickersham revealed that Bishop's divorce with Jake Malloy (Jamie Bamber) will lead to her "unravelling." According to Wickersham, Bishop is going to be "really involved in her work for the rest of the season."

 "I would imagine that she would take a little bit of time to herself, to really take a moment, think about that relationship. Relationships are hard, and I think that being alone for periods of time is important, to learn things about yourself. I think that's what Bishop will have to do," Wickersham added.

"NCIS" Season 1 episode 14 airs Feb 9 on CBS. More spoilers and updates for "Decompressed" are expected soon.
