On state-owned property near Imperial Beach, California, south of San Diego, while four Marines patrol the area (along the US-Mexico border) to support federal customs and immigration agents, unknown people for unknown reasons ambush the Marines and their Humvee; one escapes, and three remain missing; officials wonder whether the intruders are Mexican smugglers; Callen and company investigate. A search party finds the body of one Marine; the lone survivor says that one of the missing is a pregnant lance corporal, and the dead one was the father; a snitch gives a tip to G and Sam, the latter of whom checks it out while playing it cool; Nate suggests an alternate possibility; while Kensi and Deeks take a bike ride, they find something but run into trouble; G and Sam get a lift and lend a hand, then they find evidence confirming Nate's idea. G and Sam put it all together, so they confront the bad guy in charge. Nate prepares for a journey. Written by

My cover was never blown. I spent 7 months undercover working Memo Torres when he was still a cartel underling. Now he's the man. That means he's the fastes route to find those missing Marines. And the only person who can get to Torres right now, is in this box.

The man in this box has a price on his head.
