Sam? Stazek and the graduates of the police academy became police officers like their adoptive father after graduation. Soon after I started the job, a series of police officers were killed, and the killers all looked like ordinary citizens. Although he hates this cold-blooded killing, he is unwilling to use his special "talent" to prevent crime. However, when his partner was killed, he had to use his "talent". Through the autopsy of the killer's body, he found that someone was doing a crazy surgical operation to control people and turn them into killers by piercing tiny holes in people's eardrums. Now, Sam must race against the clock to dig up the man behind the scenes, or more policemen will be killed.
