The team is tasked to prevent a thief, King, from robbing antiquities stored at a Naval base. Hetty sends Kensi undercover for the task. She goes undercover posing as a highly trained burglar. The NCIS team discovers that King is looking to steal Naval technology in addition to antiquities. The technology in question had been hidden in a vase at the Naval base. A Chinese diplomat that had recently been deported had hidden it in the vase. King planned on taking the technology and the vase and selling it to the Chinese. King has hired Kensi to be on the team for this job.
King is known for killing his team as soon as a job as done. The team begins to worry after Kensi is back at King's home with the rest of the crew after finishing the job and a blast is fired. They rush to investigate the scene. After counting the dead bodies they are assured that Kensi is still alive but their channels of communication with her have been cut. They decide to head to the Naval base, the spot where King would most likely be.
Kensi is able to put her training to good use and is able to bring King over to the unit where the technology had been hidden. The team is able to come to Kensi's rescue and save the technology from being stolen. They take King into custody. Hetty then tells them that she had the vases switched so the technology was never really in danger of being stolen.
