Agents Sydney Bristow and Marcus Dixon are hot on the trail of a
drug lord who has created a mind-control drug so potent that in the
wrong hands it could be one of the world''s most dangerous
bioweapons. Determined to halt production of the substance, the
agents go undercover as dealers. Their approach proves to be
successful when the drug lord invites them to his estate -- the
perfect chance for Sydney to snoop around and find the location of
the main lab.
But things don''t go quite as planned. A government agency
interferes with APO''s mission; Sydney is forced to ingest a dose
of the drug and commanded to turn on her APO counterparts; Dixon is
taken hostage; and someone believed to be an ally turns out to be
more foe than friend....
