While a Navy rear admiral rides in a taxicab, two motorcyclists, using silenced pistols, execute both him and the cabbie; Gibbs and company investigate. Abby starts a new program, and McGee receives unusual calls. Ducky says that the target was the driver, not the admiral, because the bad guys pulled one of his teeth and lifted the fingerprints on his right hand. The driver was a political refugee who, seven years before, immigrated into the US from Burundi (in East Africa). The hackie remains a John Doe, but the gang identify a distinct trend. The team narrow their attention to a suspect, whom they find shot to death as a motorcycle zips away; they keep going, and they work it out.
