Plot Synopsis

BEFORE THEY KILL AGAIN is a one-hour docuseries that follows cops, who engage in high-stakes, one-on-one battles of wits with the most dangerous and deadly criminals, as they try to stop a madman before he kills -- or kills again -- by predicting their next moves before they strike. In these psychological life-or-death chess matches, sometimes the only option is to get inside the mind of a monster. Everyone is playing for keeps, and a single wrong move can have deadly consequences. But only one emerges victorious.
