The lives of two humans may be entangled. Due to this entanglement, the natural balance of their lives might get distorted. For instance, if one leads a luxurious life, then his entangled counterpart will be forced to live in misery as a natural consequence of quantum entanglement in the, which we presume, macroscopic world. Keil was entangled; little did he know about it until he was forced to face the irrationality.

The brutal slaughter of his parents was a cog that set the murders of his loved ones that followed in motion. Keil could not find a motive, neither to the homicide of eighteen years ago nor to the death of his best friend a couple of years ago. When his sister is murdered, Keil is desperate to stop the cog that was in motion relentlessly for the past two decades. Devastated by the loss of his only family, he is more than determined to solve the case, even if the answers he gets seem incoherent and absurd.
