Toni Collette has been cast as the lead on Netflix’s upcoming thriller series “Pieces of Her,” the streaming service announced Monday.

Here’s the official logline for the eight-episode show: In a sleepy Georgia town, a random act of violence sets off an unexpected chain of events for 30-year-old Andy Oliver and her mother Laura. Desperate for answers, Andy embarks on a dangerous journey across America, drawing her towards the dark, hidden heart of her family.

“Unbelievable” and “Knives Out” star Collette will play Laura. “Lovely, empathetic, modest – at first glance, Laura Oliver seems to be the perfect Southern woman, devoted to her work as a speech pathologist and to her disaffected daughter, Andy,” according to Netflix. “But when the ghosts of Laura’s past put her life in jeopardy, we discover there is more to Laura than meets the eye.”
