NBC's "Undercovers" unleashes plenty of clips for viewers to get a first taste of. They recount the scenes from when ex-spies Steven and Samantha Bloom were informed that their colleague had gone missing in action, to them agreeing to get back to their old job, to the launch of the mission itself.

The Blooms are a typical married couple who owns and operates a small catering company in Los Angeles with help from Samantha's easily frazzled, handful of a sister, Lizzy. Secretly, the duo were two of the best spies the CIA had ever known, until they fell in love on the job five years ago and retired.

When fellow spy and good friend Leo Nash goes missing while on the trail of a Russian arms dealer, the Blooms are reinstated by boss and agency liaison, Carlton Shaw, to locate and rescue Nash. With assistance from resourceful CIA field agent Bill Hoyt, whose professional admiration for Steven isn't hard to miss, the pair is thrust back into the world of espionage, disguises and hand-to-hand combat.

Following leads that take them to cities spanning the globe, Steven and Samantha quickly realize that perhaps this supercharged, undercover lifestyle provides exactly the kind of excitement and romance that their marriage has been missing.

Gugu Mbatha-Raw stars as Samantha while Boris Kodjoe tackles the role of the husband. As an international espionage, Mbatha-Raw is encouraged to learn many languages. "To be honest with you, I only fluently speak English," she said in an interview. "I speak a little bit of French, and I'm familiar with German because I did it at school, but everything else that I speak in the show, I learn specifically phonetically for the show."
