In a gripping narrative, a late model sedan crashes into a building in Lower Manhattan, initially presumed to be an accident or suicide, until the driver, with his last breath, claims someone's trying to kill him before the vehicle explodes. NYPD homicide detective Gray Gaynes, who witnesses the shocking event, launches an investigation that leads him into the dangerous world of self-driving cars, challenging his beliefs about the reliability of artificial intelligence. As he delves deeper, Gaynes confronts his own personal tragedies while navigating this high-stakes inquiry.
