Sebastian Logan is a successful horror writer living a quiet life on the English seaside. But soon his comfortable existence is interrupted by the appearance of an alien from the past that he hoped to leave behind forever. Together with an old acquaintance, something terrible invades Logan’s everyday life, and it relentlessly follows Sebastian. He sees strange dark figures during the day, someone else's gaze does not leave him even in his sleep. Suddenly, it’s as if he finds himself in his own novel, and the reality around him is distorted before his eyes. Logan soon learns that there are doors that lead to unknown worlds, that the nightmares that appear to us in oblivion are much more real than is commonly thought, and life after death exists, but this is not a reason for joy. And Sebastian’s attempts to get rid of the constant persecution, to understand what is happening to him, turn into mortal danger, because he is far from the first who disappeared, trying to get out from under vigilant surveillance.
