Shanghai, 2010. Three young Americans find themselves caught in the mysterious web of a man known only as "Smith." Smith's world, "Flatland," is terrifying. A place where the past and the present exist with deadly consequences.

Coventry is gone, but Khan is back, this time in the more youthful form of Noel Jagger, a slick, seductive playboy who wastes no time reclaiming his stake atop the criminal underworld of Shanghai.

Jagger gets his hands on a deadly nerve agent developed during WWII, and not long after an entire village is decimated. JT and Mitchell set out to find who is responsible, while Smith's rage reaches a boil.

With briefcase-size nuclear bombs on the black market in Shangai, Mitchell goes undercover as a potential buyer, embroiling himself in a triangle of deceit and desire that could turn deadly.

A vicious car accident puts a young boy in a coma and leads Mitchell into a divine encounter with the ancient goddess of mercy, Xian Gu. Smith dispatches JT, Linda and Amy to investigate a strain of deadly knock-off drugs.

Smith closes in on Khan who has disguised himself as the arch-criminal Richard Coventry. Caught in the middle is Amy Li, the unknowing pawn in an age-old battle between the ultimate good and the ultimate evil.

A female conjurer long ago sealed a contract with Khan, selling her soul for eternal youth, knowledge, and power. In return, the conjurer must kill Mitchell in perpetuity, a deed she has successfully performed for several hundred years.

Smith uses JT and Mitchell to put the squeeze on an accountant with connections to Jagger. To tie up his loose ends, Jagger sends Diao Li, a merciless assassin and Amy Li's long-lost father.

Both JT and Amy welcome old friends to Shanghai and are reminded of their lives before Flatland. JT's friend lures him into a tomb-raiding scheme, unknowingly awakening an invincible ancient warrior with ties to Khan.

Three mysterious women enter the lives of JT, Mitchell and Amy at the same time. All are beautiful. All are deadly. All share a secret, and only Smith knows the truth. But is he telling?

The Devil's Daughter is alive in Shanghai and with her come secrets that threaten the balance of good and evil. The battle for the girl's soul re-ignites between Amy Li, a mysterious Priest, and Simon Cross, Khan's newest persona.

The ghost of an ancient warrior is awakened in JT's loft and blames him for its murder. JT needs help from Uncle to discover whether he is indeed guilty of the crime; Amy's forbidden liaison with Jagger comes back with a vengeance.

A disturbed young woman escapes from a mental hospital, spreading insanity and fear. JT discovers the truth behind her madness, but he's too late to save Amy, Mitchell, and worst of all, Smith, from her deadly strain of paranoia.

The onset of four supernatural signs foretell the heroes' worst nightmare: the death of Smith. It's inevitable, unless Amy can defeat the Avatar, a ruthless, lightning quick warrior who arrives in Shanghai to deal the final blow.

Mitchell is trapped in a new Flatland - a twisted mirror-world where everything he knows is turned on its head. It's a nightmare reality where Khan rules with abandon, and Smith is missing.

Khan and Smith. Finally, they come face to face. The battle envelops the lives of all our characters - and comes to an ending nobody could have predicted.

A Shaolin Monk returns to the present in order to set straight a horrendous mistake he made several hundred years ago, when he unwittingly saved the life of Khan and let JT die.

A mafia vendetta catches up to Mitchell in Shanghai. Fear forces him into Flatland for the first time, where he dodges bullets all the way back to 19th century Paris. Uncle and JT teach him to control his newfound abilities.

Simon Cross pulls out all the stops in an attempt to take Smith into Flatland and force Armageddon. Amy wills her way into Flatland and discovers the horrible secret behind her relationship with Noel Jagger.

Mitchell narrowly escapes death at the hands of a pair of vengeful archangels, one of whom he may have loved in the past, while Khan and Smith maneuver their pawns into place in anticipation for one final showdown.

A series of nightmare encounters leads Amy to a frightening discovery: she was executed as a witch in the past, and the judge who sentenced her has returned for a re-trial; Mitchell and JT secretly tail Smith, hoping to glean information.
