The team will once again deal with the Russian Federation in the next episode of "NCIS: Los Angeles" season 7.

According the official synopsis for the episode titled "Matryoshka," the team needs to find out where Arkady Kolcheck (Vyto Ruginis) is located in Russia. But to be able to do this, they need the help of Arkady's daughter Anna (Bar Paly) to successfully go undercover at a gala and get an access to the computer of the Russian Consul General.

Several promo images were shared by SpoilerTV showing special agents Sam Hanna (LL Cool J) and G. Callen (Chris O'Donnell) looking dashing in their suits as they lead Anna toward the party. There is also a photo showing Callen and Anna, who were linked romantically in the past, dancing at the party.

Meanwhile, the partners-turned-lovers Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen) will wear waiters' uniforms while looking for clues that will lead them closer to Arkady's location.

The upcoming episode is considered the first part of a two-episode special that will take the members of the team to Russia.

The team first blamed Arkady for the death of some of the agents working with Callen during the Operation Cossack in Russia, but he later on proved that he is trustworthy when he left the KGB and settled in Los Angeles to set up his own private security firm. He also helped Callen get several vital information whenever the team needed to investigate several Russian operatives.

Meanwhile, the second half of the two-part special involving the Russian Federation remains under wraps. The show will also take a short hiatus after the "Matryoshka" episode as the seventh season premiere "Active Measures" will be broadcasted on Saturday, Feb. 20.

"Matryoshka" will air on Monday, Feb. 8, on CBS.
