'Leave your daughter with me, or I will kill you both.'

It felt like any other evening before Karl and his daughter were ambushed by a figure in a blank mask. A knife is put to her throat, and Karl is forced to make an impossible decision. Stay and die, or walk away and take this thug's word that they will both will live.

Should he trust a villain and leave his daughter with a knife at her throat? Could he ever live with himself if he did?

It's not long before more seemingly unconnected and innocent people across London are offered a deal in exchange for their life. More blood is spilled, more families shattered, and more people are left to suffer with the consequences of their decisions.
