NCIS's LAPD liaison, detective and lawyer Marty Deeks, went missing undercover just after target, drug and extortion street gang leader Emilio Philip Ortega, and his bodyguard, Luis Manuel Fellano, were killed by a bomb in their car. Deeks posed as real estate expert to approach Serbian human trafficker Radovan Lazik, who hired Ortega for his smuggling contacts. LAPD detective Jess Traynor, Deeks's partner, dies from a similar car bomb just after briefing NCIS. Detective Frank Scarli is in charge for LAPD, which aborted the undercover operation. Marty contacts Hetty, lightly wounded, asking help to get Lazik.
