Plot Synopsis

TRIAL 4 is an eight-episode true-crime documentary series that tells the story of Sean K. Ellis, who was charged as a teen in the 1993 killing of Boston Police Detective John Mulligan, served 22 years in prison, and now fights to prove his innocence while exposing police corruption and systemic racism. Though law enforcement presented evidence linking Ellis to the murder, further investigation revealed corrupt police officers, questionable witnesses and enormous pressure within the department to solve the case. Ellis's story, while devastating, sheds light on timely issues of systemic racism, police corruption and criminal justice reform while offering hope that, ultimately, people have the power to change the system. On Wednesday, November 11, 2020 at 3:01am ET/12:01am PT, Netflix released all eight episodes of TRIAL 4.
