'Making a Murderer' Part 2 Trailer Previews Post-Conviction Process

The first trailer for the second part of Netflix's Making a Murderer has arrived to preview the post-conviction process for Steven Avery, his co-defendant, and nephew Brendan Dassey and their families.

"When everything is in question, what will be uncovered?" the trailer asks, showing footage of the legal teams hard at work on the case. 

Introduced in the trailer is Avery's post-conviction lawyer, Kathleen Zellner, as she looks to prove that he was wrongly convicted. "If this case is solid, if he's guilty, I'll fail," Zellner says.

The second part of filmmakers Laura Ricciardi and Moira Demos' hit documentary series comes nearly three years after its initial premiere in 2015, before going on to become a global phenomenon. Part two of Making a Murderer premieres Oct. 19 on Netflix.
