The Serpent

In 1975, Dutch diplomat Herman Knippenberg investigates the disappearance of two backpackers who were last seen alive at the Bangkok apartment of gem dealer Charles Sobhraj.

Marie-Andrée Leclerc leaves her life behind for the love of Charles Sobhraj but discovers the chilling cost; in spite of obstruction, Herman Knippenberg vows to investigate the murders of the Dutch couple at great risk to his career.

Adventure brings young Frenchman Dominique Renelleau to Kanit House where he finds himself trapped in Charles Sobhraj's lair; as he listens to testimony, Herman Knippenberg realizes the scale of Charles's crimes.

Charles tightens his grip as Marie-Andrée plays along and Ajay Chowdhury takes a trip; Nadine Gires goes undercover.

Nadine must keep the poisonous crew in the nest on the brink of a big raid, but Charles has a backup plan.

Charles makes bold moves while a still-obsessed Herman tries to forget; Marie-Andrée and Ajay fight over their future -- by the mastermind's side.
