Netflix's new social thriller "What/If" will explore the ripple effects of what happens when acceptable people start doing unacceptable things. 

Each season will tackle a different morality tale inspired by culturally consequential source material, and the power of a single fateful decision to change the trajectory of an entire life.

The 10-episode series stars Academy Award-winner Renée Zellweger (Cold Mountain, Jerry Maguire, Chicago, Bridget Jones movies) in the role of Anne. In her distinguished career she has also received three Golden Globe and SAG awards.

Mike Kelley, who created ABC's Revenge and CBS' "Swingtown," came up with the idea for the project and will serve as showrunner and write the series. 

According to Hollywood Reporter, "What/If" is Zellweger's first-ever TV series-regular role. Before this, her largest TV commitment had been the lead in 1992's USA Network telepic "A Taste for Killing," which also marked her acting debut.

A release date is yet to be confirmed.
