The Admiral's Daughter

Tony is assigned to escort Amanda, the daughter of the Vice Chairman of the Joint Chiefs of Staff from Marseille due to her extravagant partying ways but when he reaches the local NCIS office he finds all the employees and agents dead but he and Amanda find themselves on the run from a rogue French policewoman. The team back home work on a supposedly separate case involving a corpse found in a septic tank at Norfolk with a link to Amanda's father. Things become complicated when Tony discovers that Amanda's party-girl persona was a mere cover for her work with the Defense Clandestine Service.
