Following the death of the Leigh family matriarch, Annie and her children uncover disturbing secrets about their heritage. Their daily lives are not only impacted, but they also become entangled in a chilling fate from which they cannot escape, driving them to the brink of madness.

The Testaments is based on Margaret Atwood's Booker Prize-winning novel of the same name, which was published in 2019 and takes place in the dystopian theocracy of Gilead. Years after the events of The Handmaid's Tale, The Testaments is a coming of age story that finds a new generation of young women in Gilead grappling with the bleak future that awaits them. For these young women, growing up in Gilead is all they have ever known, having no tangible memories of the outside world prior to their indoctrination into this life. Facing the prospect of being married off and living a life of servitude, they will be forced to search for allies, both new and old, to help in their fight for freedom and the life they deserve.
