Mostly based on the murderous conmen duo Charles Sobhraj and Marie-Andrée Leclerc (played by Tahar Rahim and Jenna Coleman) The Serpent dives into their extravagant and horrific lives as they con and kill their way through the “Hippie Trail” in Asia in the 70’s.  A blend of venomous large gummi worms, Swedish skulls and sour cola dummies complement this crime serial.
