Odyssey follows Natasha Flynn, a sharp-tongued, coke-fuelled London estate agent, who juggles debts, danger, and deception. Her seemingly glossy life—flashy clothes, posh loft apartment, and endless champagne—hides a spiralling mess of broken dreams, addiction and a business on the brink of collapse. Enter Dan and Will, smooth-talking loan sharks with a sinister edge. Their offer? Easy cash, if she hides a kidnapped fellow estate agent. What follows is a wild, neon-soaked ride through London’s seedy underbelly, as Natasha searches for The Viking, an old ally with violent tendencies. A bloody, chaotic showdown ensues, leaving bodies—and morals—shattered.
For her first day of orientation, Dr. Tristian Mackenzie makes her way to the Silverdale Psychiatric Hospital for the criminally insane, where she learns of the strange series of cases from the similarly strange Dr. Moon.
