When fear is used as a weapon, the panic paralyses the target like a spider web which immobilizes the preys in the last seconds of their existences. Thenceforth, eliminating a life becomes something elementary.

Rio de Janeiro had already experienced the climate of terror at the end of 2010, with cars and buses being constantly torched overnight. Now, a similar climate settles in the city, but this time the targets have names and surnames. Hundreds of thousands of people are progressively threatened by terrorists who seem to know all the details of their lives. Some of them are cowardly murdered, in a demonstration that anyone can die.

Matheus Erming is the Computer Forensics specialist responsible for examining the computers used by the victims and for finding out how details of their daily routines, kinship and friendship relations were taken by the perpetrators of the attacks. The investigations are the starting point of a persecution not only cybernetic, which touches the lower levels of the organized crime and chases for the roots of chaos in the city. During this search, the security of Matheus' family is also put at risk. When this happens, he knows he has only one choice: to go further, at any cost.
