Under the cover of night, a distant stranger plays the piano. Meanwhile, in a nearby hillside prison, a resentful inmate who has been betrayed gazes at the cityscape from behind bars. He is plotting his revenge, and the vengeful killer is preparing to make his escape. Vares, a private investigator, takes on a new client. Despite the allure of the client’s beautiful wife, Vares senses something is amiss. As summer night falls, a gunshot echoes through the air. A life is abruptly ended, altering the course of Vares’ investigation. His search for answers takes him to face-to-face encounters and second-hand bookstores; a trip to the gym uncovers a drug-smuggling operation originating from Stockholm. Vares becomes ensnared in a web of illicit money and luxurious silk. All the while, a sly garter snake lurks in the shadows.
