Leandro Karambatos, a sales manager and emerging writer who just won the Madrid Noir contest, is acclaimed for his narrative but discovers that literary recognition has disconnected him from his previous, empty, and meaningless life. In Mexico City, where chaos and normalcy intertwine, Leandro adopts an aggressive dog he decides to save from euthanasia, not realizing that one afternoon, Lecter, his dog, kills Acia, Leandro’s ex-girlfriend. Fearful of losing his dog, Leandro hides the body and plunges into a spiral of guilt, paranoia, and hallucinations.
The bite from Lecter, which Leandro initially ignored, begins to unravel his sanity, as the past, his mistakes, and the weight of guilt lead him to relapse into his old addictions. In a world that seems to be changing before his eyes—where zeppelins cross the skies and funiculars replace buses—Leandro faces police pursuit, a city hiding its own secrets, and the ghosts of his novel beginning to manifest in his everyday life.
Leandro fights to keep Lecter alive, convinced that saving his dog is the only thing that can redeem him. But as the line between fiction and reality blurs, he becomes entangled in a web of secrets, lies, and delusions. It all culminates during a live interview when an unexpected question reveals the truth: is his new novel more than fiction? With the police closing in and his mind fracturing, Leandro seeks one last chance at redemption, while Christmas becomes the backdrop of his desperate escape.
