Through various means of misdirection, Bourne soon chases The Professor down and shoots him twice, mortally wounding him. Bourne shoots a fuel tank to provide an obfuscating explosion and smoke. It turns out that an “asset” like Bourne, called “The Professor” (Clive Owen), has tracked him down and has his sights set on him.
He tells everyone to get in the basement and grabs a shotgun on his way out of the door. The pair recuperate, but Bourne's sixth sense for danger is triggered when the family dog goes missing. Said old flame, Eamon (Tim Dutton), unexpectedly shows up with his children and dog in tow.
After evading the French police and pulling off some sick moves in a battered Mini Cooper, Bourne and Marie (Franka Potente) take refuge in an old French farmhouse, belonging to an old flame of Marie's.
