'The Sinner' Season 4: Two Actors Returned, Six New Stars Joined Main Cast

The fourth and final season of the USA series The Sinner is now streaming on Netflix and the show is bound to gain a lot more viewers!

The show always airs first on the USA Network, but each season has gained an even bigger audience when it debuts on Netflix.

Season four of The Sinner previously aired on cable television a full year ago and now it’s available on the streaming service.

For the first time, two actors returned instead of just series star Bill Pullman, who plays the now-retired Harry Ambrose, who is on vacation on Hanover Island in Northern Maine. When an unexpected tragedy occurs involving the daughter of a prominent island family, Ambrose is recruited to help the investigation, only to be thrown into a mystery of mounting paranoia that will turn this sleepy tourist island, and Ambrose’s life, upside down.

Alongside the two returning stars, six actors were added to the main cast for season four.
