USA officially greenlit The Sinner season 4 in June 2020, so what will new episodes be about and when will they release? Based on Petra Hammesfahr's novel of the same name, the anthology series stars Bill Pullman as Harry Ambrose, a detective in Dorchester, New York. The Sinner season 3 premiered in February 2020 and concluded the following month after an eight-episode run.

The Sinner season 3 follows Ambrose's attempts to solve the death of Nick Haas (Chris Messina), a man who dies in a car accident upon reuniting with college buddy Jamie Burns (Matt Bomer). Ambrose quickly identifies Burns as a person of interest, and learns that Haas urged him to kill for sport. The Sinner season 3 turns into a Dostoevskian character study a la Crime and Punishment, with Ambrose even allowing himself to be buried alive while hoping to earn Burns' trust.

Ambrose betrays Burns in the penultimate episode of The Sinner season 3, and manages to record the killer's confession. But when said confession is deemed inadmissible in court, Burns seeks revenge and kills Ambrose's captain, and even threatens to kill several more people. Here's everything know so far about The Sinner season 4.

The Sinner season 4 will reportedly premiere in 2021. Based on previous release schedules, it seems likely that The Sinner season 4 premiere will air at the beginning of August 2021, which would align with the release dates for the first two installments. If USA sticks with a Thursday slot, expect The Sinner season 4 to premiere on August 5, 2021 and run through September 23, 2021. That being said, it's possible that production may be delayed due to the ongoing coronavirus pandemic.

The Sinner Season 4 Story Details

The Sinner season 3 ends with Ambrose killing Burns after several intense confrontations. For the continued storyline, what's important is the psychological damage that Ambrose endures, evidenced by the final moments that show him sobbing while speaking with Sonya Barzel (Jessica Hecht), who wants to know all the specific about Burns' demeanor before death. "He was scared," Ambrose says - a moment that captures his own life uncertainty, both personally and professionally. Ambrose returns to work, but feels guilty for killing Burns rather than calling for back-up.

For The Sinner season 4, expect USA to bring in another round of new cast members, alongside Pullman's return as the central protagonist. Will Ambrose stay on the level, or will he give into dark thoughts and actions? That will all seemingly depend on his ability to maintain a healthy romantic relationship, whether it's with Sonya or someone else. Ambrose gets the job done at work, but his life experiences have created a complicated worldview.
