This is Jessica Biel's first leading role in a TV series.

Premiered during the TriBeCa Film Festival on April 25, 2017.

Jessica Biel was nominated for the 2018 Emmy Award in the Lead Actress in a Limited Series or Movie category for her role as Cora Tannetti in The Sinner (2017), but lost to Regina King from Seven Seconds (2018).

The song "Hugging & Kissing" by Big Black Delta features heavily throughout the first season. It's vital to the plot.

Originally developed as a one season 'Limited TV Series', however, USA Network was so pleased with the ratings they wanted the writers/producers to develop a season 2. Although still considered a 'Limited Series', it has morphed into an 'Anthology Series'. Bill Pullman's detective character from season 1 returns, along with a new mystery solve, and primarily new cast. Jessica Biel is as an Executive Producer.
