Located in Los Angeles, California is the Office of Special Projects (OSP) an undercover division of NCIS. The team consists of NCIS Special Agent G. Allen (Chris O'Donnell), a chameleon who manages to alter himself into any person that he needs to be in order to blend in with the criminal underground. His friend and partner Special Agent Sam Hanna (LL Cool J) is also a former U.S. Navy Seal. These two agents work as a unit, using state-of-the-art surveillance equipment to solve crimes. They report back to the OSP team leader, Special Agent Lara Macy (Louise Lombard). Collaborating with them are Special Agent Kensi LO (Daniela Ruah), and Operational Psychologist Nate Getz (Peter Cambo). Together this team does what they must to defend interests on a national scale.
