Dateline

A popular and attractive young woman, Robin Hoynes is murdered while working at a fast food franchise in 1984. There are few clues, except a strange and un-explainable piece of foam found at the crime scene.

Wisconsin, 2017: Teresa Halbach, murdered in 2005, was the victim in the Netflix 10-part documentary Making a Murderer (MaM), which became a Netflix binge-watching phenomenon in 2015. Steven Avery and Brendan Dassey were convicted in 2007 to life in prison for the murder. This updates the case with surprising information not included in MaM. Lead investigator Tom Fassbender, who interrogated Dassey and some believe produced a false confession, is on camera for the first time defending his actions and the prosecution's evidence.
