The highly popular spinoff of the original "NCIS" series "NCIS: Los Angeles" has earned the right to be called "great television."

According to Spoilers Guide, in Episode 24, which airs on May 18 at 10 p.m., the team must now travel to Moscow and assume different identities to pursue their suspect in the Arkady case.

It is Arkady's personal connection with an oil tanker that leads them there. And on foreign soil, anything can go wrong without the protections of domestic U.S. laws backing them. But fighting terrorism is a risk they are willing to take.

While the team is undercover in Russia, Callen will also uncover new information that he has a personal connection with. This personal information could be the clue to him finding out who his father really is, or what he has done.

In an interview with CBS, LL Cool J gave a little insight into playing his character, Hanna, on the show.

"He's a character that believes in protecting his family, he believes in protecting his country, his way of life, he's loyal, he has integrity, he puts his life on the line every day, to persevere and protect the freedoms of the innocent," LL Cool J told CBS. "And there are people like him all around the world and especially in America there are members of the military and also different law enforcement agencies who put their lives on the line every day to make the world a better place."

He also spoke a little about the training he received before playing the role and what his real life counterparts go through.

"Well I'll tell you one thing, it takes more than big muscles to do that job. It takes a lot of brain power, it takes a lot of intestinal fortitude, it takes a lot of will-power," he said. "I went down (to) Camp Pendleton and met with some of the Special Ops guys, some of the sailors and Marines and took a tour of the base and saw them doing exercises and stuff like that."
