Sam is convinced that the theft of software for a new unmanned aerial vehicle is connected with the disappearance of the lead engineer's 10-year-old daughter, a girl Sam once provided protection detail for in Saudi Arabia.
Granger doesn't believe in the connection, but Sam and the team continue to pursue it and he was right.
The mother was blackmailed into helping them activate the UAV software in order to keep her kidnapped husband and daughter safe. NCIS tracks her down and saves the day.
