Des

With limited resources, Jay and the police continue to dig into Nilsen's memories in an effort to convict him for the murder of every one of his victims. But when Des withdraws his cooperation and stops talking, Jay fears justice will be lost.

Reeling from Des' change in plea, Jay and the police throw themselves into proving premeditation. If they can show the court that Des was undoubtedly of sound mind when he committed his crimes, he will go down and never be released.
