On the 50th floor of a towering glass skyscraper lies the office of Salem, the CEO of a major tech company. The office is completely soundproof and equipped with a smart system that controls the lighting and blinds. At exactly 8:50 PM, a piercing scream was heard. Building security rushed in to find Salem's wife standing in shock, the lights on, and Salem dead from a heavy blow to the back of his head, sitting in his chair facing the massive panoramic window. The floor was nearly empty, but investigations revealed a web of lies and ulterior motives among six people present in the building that night. The timeline of events is complex, and every second holds a secret.
