Juan de los Santos, a former undercover cop from Paraguay, once ready to take down the biggest drug cartel in Latin America, has lost everything; his wife and kids brutally murdered on a cold dark night and with them, his will to live. Juan, himself didn't survive unscathed; on that cold night he took two bullets, one still in his heart, the other one damaging a part of his brain, cursing him sporadic amnesia. In an internal and external struggle with his own demons, Juan must defeat incredible odds to save innocent people. Sleepless, and afflicted by treacherous nightmares of that night, he is willing to take any job to alleviate his suffering.

In a future where a special police unit is able to arrest murderers before they commit their crimes, an officer from that unit is himself accused of a future murder.
