The gripping true-crime docuseries arrives on Netflix this November.

Docuseries 'Trial 4' will follow the true story of one man's fight to be proven innocent in a Boston court. Convicted in 1995 following two mistrials, Sean K. Ellis has spent 22 years in prison for a crime he didn't commit.

After being unjustly convicted of murdering Boston Police Detective John Mulligan in 1993, when he was just 19 years old, Ellis was incarcerated for over two decades.

The Boston man, who at the time of filming was facing his 4th trial for murdering the police officer, will finally have his story told in the new Netflix series. Throughout the eight episodes, we will witness Ellis fights to prove his innocence, and attempt to expose the police corruption that put him away in jail for all those years.

Here's the official synopsis:

The eight-episode docuseries 'Trial 4' delves into the story of Sean Ellis, a man who served 22 years in prison after being found guilty of killing Boston Police Detective John Mulligan in 1993. 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.

And here's the trailer.

'Trial 4' will drop on Netflix November 11.
