An appalling betrayal among the CIS team is about to be discovered. Still unnamed, the CIA L.A. agents will drop their jaws upon knowing that the traitor is someone they least expected. Meanwhile, Kensi still remains captive by the mole who continues to torture her. The agents though are to come up with a rescue plan that may bring her out either dead or alive.

After over a month of hiatus, the "NCIS: Los Angeles" is finally coming back with its season finale on Sunday, Feb. 19. The latest spoilers to surface about the "NCIS: Los Angeles" season 8, episode 15 reveal that one agent in the NCIS is apparently backstabbing the rest of the team. A traitor among them will be found out by one of the male members of NCIS L.A. Who among them is bringing the team at risk is still greatly kept under the wraps, hence the identity of the traitor and how it tries to turn down the team still remains as a shocker.

There was a theory though that recently went out, claiming that the betrayal will have a connection to the mole incident. Some are suspecting that the traitor refers to the mole who apparently works with the NCIS L.A. team, hence their difficulties in finding out the culprit's identity and location.

Meanwhile, the episode 14 of "NCIS: Los Angeles" revealed that Kensi has been kidnapped by the mole. She is kept in a location that remains unknown to the NCIS L.A. team. A heavy torture session is being inflicted on the captive, and the team is already distressed as to how they can formulate a rescue plan. The agents though reportedly have to find a way as soon as possible to save the life of Kensi who is in danger of being beaten to death.

A theory on "NCIS: Los Angeles" though states that Marty Deeks will save Kensi from harm. Their relationship is reportedly a driving force for the former to come to the latter's rescue, hence fans might see a sweet reunion of the two.

"NCIS: Los Angeles" airs on Sundays on CBS.
