Twin Peaks and The Mindy Project alum Joy Nash has signed on to star in AMC's adaptation of Sarai Walker's 2015 novel, Dietland.

"Nash plays Plum Kettle, obese all her life and preparing for lap band surgery when her world is upturned by two rival feminist factions," explained a synopsis from the cable network. "Caught between old ideas and radical new extremes, Plum must decide for herself what it means to be a revolutionary as the 'war of the sexes' becomes literal."

Marti Noxon will be the beauty-industry drama's executive producer, writer and showrunner. She will also direct multiple episodes of the co-production between AMC Studios and Skydance Television.

The 10-episode, first season is scheduled to debut in 2018.

"Joy is everything I hoped we'd find in our leading woman -- beautiful, smart and blazing with talent," said Noxon in a statement. "When she auditioned the whole room was electrified. I can't wait for the world to meet her Plum."
