Flynn, an honorably discharged Marine with a mixed record, now an employee of Citdential, a multinational civilian security firm under contract to the US government, returns to the USA from work in Baghdad, now accused of having killed an Iraqi businessman whom he had a duty to protect; when Flynn arrives at the LAX airport, a Citdential detail tries but fails to intercept him, and a company agent dies during the process; Director Vance tasks the Callen team to find Flynn fast. G and Sam check out tats and chicks, Kensi and Dom find a body, and Eric produces at the office, then the four musketeers wait and watch; Kensi offers to call a tow truck. Citdential guys mess up a meet. The gang finish sorting out the pieces and putting them together, then a major confrontation takes place on a sidewalk, but G and Sam (having learned what really happened in Iraq) hold the winning hand, so they come out on top; finally G gives Flynn a ride.
