The story begins with Sara, a young UN volunteer, traveling through Central Africa on the Katangasi Express. Her presence on the train draws unwanted attention, and things quickly take a dark turn when the local police board the train and arrest her on false charges of prostitution. Despite her protests, Sara is shackled and taken away, marking the beginning of her descent into a world of horror.

Upon arrival at General Biongo's Prison Camp, Sara is thrown into a brutal and dehumanizing environment ruled by the monstrous Warden Totongo. Her first encounter with the sadistic warden is a terrifying ordeal as she is forced to strip and endure a humiliating search. Totongo's twisted mind sees her as either a prostitute or a drug smuggler, and he treats her with absolute cruelty, setting the stage for the nightmare that will become her life.

That same night, Sara is forced to dress provocatively and summoned to an intimate dinner with Warden Totongo. The young volunteer is filled with dread, knowing that this dinner is just the beginning of her torment. As she trembles in fear, the night stretches into an endless nightmare, where Sara's will and spirit are tested to their limits by the sadistic warden, marking the start of her relentless suffering in the camp.
