Mindhunter is the new television series on Netflix from the minds of David Fincher and creator Joe Penhall. Based on the books of real life FBI agents John E. Douglas and Mark Olshaker, the series follows fictionalized versions of these men in agents Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany) in the late 1970s on their journey of creating the Elite Serail Crime unit born from criminal sciences regarding serial killers. The idea that young Ford brings into Tench's world is that by conducting various interviews with multiple murderers, trying to understand their psychology might be the key into these insane men's (as the show remarks multiple times: it is generally men that commit these acts) mind and thus develop a method to better understand, investigate and prevent these killings.
