The Ghost -- a legendary figure who has gone by some many aliases that his real identity is a mystery -- has created a hallucinogen that is both a blessing to psychiatry and a powerful weapon that can ignite mass-hysteria. Agent Sydney Bristow must learn who has stolen the drug and sold it to a chemical weapons dealer in Mexico City.
But Sydney's father (also a CIA operative) shares a past with The Ghost. In fact, he thought he killed the man in a Vietnam jungle years ago. Now Jack must discover if his mind is playing tricks on him or if their wartime encounter was just another one of The Ghost's twisted psychological experiments...
