With foreign civilian passengers Harm and Beth land a damaged C-130 aboard USS Seahawk. A Navy seaman, having converted to the Islamic faith, stands accused of taking part in al-Qaeda activities; Sturgis and Bud prosecute, and Mac defends.

Sturgis helps a US submarine with 10 survivors of the sinking of a North Korean midget submarine, and Harm helps (as do Mac and the admiral) an underprivileged WW2-era Navy veteran with a legal problem. Harm stays in touch with Mattie.
