Puppet

What would a hypnotist do when he sets out to take revenge?

A string of bizarre murders has taken place. Every killer commits suicide at the crime scene, their bodies bearing severe corrosive injuries, their faces and fingerprints erased. The criminal manages to carry out a series of murders without ever showing himself. Later investigations reveal that these people were merely his test subjects. His ultimate goal is far more significant than that.

A once-brilliant psychology expert, an extremely cruel murderer, and a patient with schizophrenia: now, he is a key investigator on this case. Can he find the real culprit? Or is there something else going on?

Hypnosis seems mysterious, but it's actually quite simple. You speak to someone while they sleep and suggest certain things to them. When they wake up, they won't remember what they heard, but the effects of your words will be easy to see. You can try suggesting that the first thing they do in the morning is open a drawer. When they wake up and open it, ask why they did that, and they'll naturally say they were looking for something. That's hypnosis.
