The Ancient Affair revolves around Dr. Seta Nzapa, an infectious disease specialist and Special Agent Bo Jin of the Federal Bureau of Investigation. During a scientific research mission on a remote south pacific island Dr. Seta Nzapa sits down with a tribal elder who tells her an incredible story of a place called the Bitter Waters. She leads an expedition into the dark dangerous jungle of New Caledonia in search of the mysterious place and makes a remarkable discovery. Several months later at a medical symposium in Greece where she is the guest speaker she meets and falls in love with an FBI agent on assignment. Chinese-American FBI Special agent Bo Jin is on an international manhunt to catch an elusive assassin. He joins the Greek police investigating the killing of three Serbian war criminals on a clandestine flight back to their homeland. The three men are murdered in a manner no law enforcement on the planet has ever seen before. The killer parachutes out of the aircraft leaving the Serbian soldiers to a fate destined to the bottom of the Aegean Sea. But, it is only the beginning as more and more men across the globe are falling victim to this cunning assassin. The only thing they seem to have in common is the manner in which they meet their demise. The mystery deepens when construction workers dig up mass graves of young boys that were killed back in the sixties and seventies in a small rural Georgia town. As bodies begin to pile up, Seta, Agent Jin and his partner try to make the connection between the child murders decades ago and the killings today. Their investigation uncovers a terrifying plot by an ancient secret society's diabolical scheme to destroy mankind.
