At the end of September, Netflix announced Making a Murderer: Part 2 would premiere Oct. 19. Now there's a dramatic three-minute trailer that shows how the second installment of the true crime docuseries will address the aftermath of Steven Avery's story going nationwide on the streaming service back in December 2015.

Three years after the first season captivated audiences, this batch of episodes arrives to follow the legal teams of Steven Avery and his nephew Brendan Dassey as they attempt to exonerate their clients for the murder of Teresa Halbach in 2005. "I have one goal, and that's to overturn the conviction of Steven Avery,” lawyer Kathleen Zellner says in the trailer. “If this case is solid, if he's guilty, I'll fail.” Zellner is a new lawyer for Avery who specializes in wrongful convictions.

The trailer makes it seem like new evidence could aid Avery’s case, including the continued possibility that police framed Avery and coerced his nephew into a confession. "The prosecution's case was that Teresa never left the property, but the last call pings off a cell phone tower miles away from the Avery property," Zellner says. "There's an abundance of evidence. This could flip the whole case."

However, we know that Avery continues to serve his life sentence, after a Circuit Court Judge Angela Sutkiewicz denied his request for a new trial almost a year ago. We also know that the U.S. Seventh Circuit of Appeals ruled Dassey’s confession was not coerced, and he remains behind bars.

“Steven and Brendan, their families and their legal and investigative teams have once again graciously granted us access, giving us a window into the complex web of American criminal justice,” creators Ricciardi and Demos told Variety last month. “Building on Part 1, which documented the experience of the accused, in Part 2, we have chronicled the experience of the convicted and imprisoned, two men each serving life sentences for crimes they maintain they did not commit. We are thrilled to be able to share this new phase of the journey with viewers.”
