Robbers rob an art-storage facility and a guard is shot. Roundtree meets Kilbride's assistant, Shyla Dahr. That facility is where Katya has a storage vault for which OSP has been seeking a warrant. Deeks and Kensi discover that Rosa has been placed with a distant relative. Katya's items were stolen in the theft. Katya used a Callen deep fake to have the warrant held. Kensi asks Kim Cho to look into the art theft for her. Appraiser Elena was the inside person for the theft who arranged for the plumber to arrive at a specific time. Kim identifies Gerard Dupont as the person who bribed Elena. Fatima and Callen capture Dupont at his daughter's pottery shop. Fatima can't keep Dupont cuffed. He denies having any part in the heist. The missing artwork isn't at either the shop or Dupont's home. Kensi and Deeks find a stolen statue at his home though. He admits he was hired by Katya. Dupont took much more than she asked for and sold everything to Hieronymous. Callen has Dupont set up a buy for some of the pieces. Hieronymous is holding an auction instead of giving Callen a private viewing. Dupont says the item from Katya's vault wasn't there. He had supplied a counterfeit for it instead. Fatima and Roundtree helped Callen bust the auction. Dupont escapes. Hieronymous had tossed the items from Katya's vault. Callen recovers a reel of film. Rosa left a worry doll for Kensi with Pilar. Kensi gives it back to Pilar, who lost hers, to keep. Deeks and Kensi stay to talk with her. The film shows a painful Noble Maidens training session. Callen recalls a similar training session.
