When the retired top female agent "Nightingale" returned to her old career to save her husband, she discovered that she was the real target of this global hunt. Chen An, an ordinary engineer, is forced to face his wife's dual identity in the smoke of prisoner robbery in the court - she is not only his Lin Wan, but also a ghost codenamed "Nightingale" who holds the secret to subvert the world.
A key, blood-stained Southeast Asia. The transnational conspiracy "Ark" has surfaced, and the shadow of trial and purge has enveloped all living beings. For love and survival, Chen An went from passive escape to active counterattack. He formed a dangerous alliance with the police chief whose identity was a mystery and the traitor "Raven" who was both friend and foe. In the dark alleys of Phnom Penh, the ruins of Angkor, and the waves of the Mekong River, he launched an ultimate gamble concerning the fate of mankind.
When the key is finally unlocked, is it a glimmer of hope or a deeper despair? Can love and trust be reborn on the ruins of betrayal?
