In just about two weeks from now, we will embark on a dangerous journey with Bella Heathcote in order to discover what sort of dark secrets her onscreen mother Toni Collette is hiding. The duo stars in Pieces of Her, a Netflix thriller about a mother-daughter relationship that is brutally changed after both of them experience a traumatic event. Back in January, Netflix released some first-look images that showcased the possible twists and turns of the story, and now the official trailer unveils further details of the plot.

The trailer showcases the ways in which Andy (Heathcote) and Laura's (Collette) relationship starts deteriorating after the mother reacts in a whole unexpected way to a shooter invading a diner. Andy goes on to investigate her mother's past and, the more she uncovers, the more she feels like she has no idea who Laura is. The trailer also teases Laura's transformation from a loving mother into a mysterious figure whose expressions get less and less revealing as the story progresses. Is she a secret agent? Is she a criminal? We'll have to wait a couple of weeks to find out.

Pieces of Her is inspired by the best-selling novel by author Karin Slaughter. The story is adapted by showrunner and Emmy nominee Charlotte Stoudt. The screenwriter has worked on thriller stories for some years: she was a story editor and screenwriter for several episodes of Showtime’s Homeland and Netflix’s House of Cards.
