Upon hearing her long-lost daughter is trapped in Mexico, Jaden Hawke contacts her lover, ex-CIA field officer, Stephan Peltzini. Lt. Drummond, the RAND Service, and detectives from San Diego P.D., join Pelztini to search for Jaden's Grace.

Grace Sanchez is fleeing probation and suspicion that a Mexican cartel is after her and her father, as she crosses into Mexico at the San Ysidro border. When border agents notice she was born in Tijuana, she is sent to a detention center. After the RAND Service detectives hear a frantic message from Jaden Hawke's daughter, they are reminded of the Gold Coins Case and kick-start a search and rescue operation.

Rand and Sparky, are reluctant to begin the search because they speak little Spanish and have no Border Patrol connections. When they call Jaden Hawke's attorney, Kale Davenport suggests Stephan Peltzini might be helpful because he speaks several languages and has a military background. As a result, Peltzini and the detectives form a taskforce, determined to find Jaden's Grace.
