An old and never resolved dream comes back to haunt Jonas's mind for a night after years submerged into oblivion in the depths of his subconscious. After returning from work, he receives a call from his best friend, saying that the two were invited to a party at a glamorous hotel outside the city.
Upon arriving at the party, he is faced with a splendid and extravagant place, failing to understand how its owners could keep such structure a secret. Right at the reception, a beautiful woman catches his eye and Jonas sets his mind to get to know her better. However, the place's nuances end up being more quirky than he could have imagined.
The first surprise comes when he is invited to partake in a lucid dreaming session, joined by the host and the woman from the reception, who apparently are a very odd couple. Jonas is supposed to take a synthetically designed drug before joining the experience, which is given to him by Rodrigo, his best friend. The lucid dream experience leaves Jonas astonished by the extraordinary that was presented to him within the mechanism of the Dream Room, but Rodrigo messes up when changing the designed drug for a simple headache pill.
From then on, Jonas starts having psychotic episodes where he alternates between two distinct realities, not knowing which is the right one and which is the dream, he goes on living lost between a maze inside the Dartagnan Brothers' Hotel and a red room where he he is stuck to a bed, being watched by the party's host, a mercenary doctor, a perverted priest, and a woman who seems to have old quarrels to settle with him.
Gradually Jonas realizes what he did in the past to be trapped like that, discovering, after making friends with the host's long stranded brother in the maze, that his life is being hunted by a religious organisation. Jonas is surprised by a tangle of news about a new world that is presented to him, full of lucid dreams and drugs.
