Psych Incisionist

What if at a certain age we go to visit our doctors and they implant strings into our hands and legs, controling us like puppets, we are pretty much free to do what we want with only one minor problem, the strings attached to us only allow us to travel so far. The strings cannot be penetrated or cut by any pair of scissors. The idea is that the doctors begin playing God with God's real creatures. The doctor has control of the strings and decides when and who should be next to die. One doctor in particular runs a death making business, he is in it to kill because no one would ever suspect the doctor and no trace can ever be linked to the doctor as proof he even killed at all. All the doctor has to do is find a way to cut the strings of his patients without leaving any actual physical mark. Everything for the doctor goes smoothly until a young teenage boy named Noah with an acute case of psychosomatic disorder as well as mental disorder involving frequent suicide attempts, Noah checks into the hospital where the lunatic doctor is working on his latest suitable death device and Noah just might be next to be in the grips of that insane methodical serial killer. The doctor agrees to take on Noah's case as his first top priority, The doctor begins drugging Noah's food and water, during psychiatric treatment therapy sessions Noah had been drinking glasses of water from a large jug of water which was laced with chemicals, the doctor convinces Noah is insane. Noah starts having visions and these visions give him warning but Noah doesn't listen, in one therapy session Noah starts to hallucinate badly and seeing images that horrified him, like his doctor morphing from human into Satan demonic force, and behind him the room grew very dark, the fireplace next to the chair where the doctor sat in lit up in a blaze which casted the entire room into a bright burning red, Noah even felt the temperature increase.
