The Testaments may have only just landed, but here's everything you need to know about when the next episode will be available.

The dystopian drama serves as a sequel to the Emmy-winning series The Handmaid's Tale and delivered a shocking twist after Disney+ and Hulu dropped the first three episodes for viewers to watch back-to-back, reports the Mirror.

The Testaments episode four is titled Green Tea and will be arriving on Hulu and Disney+ on Wednesday, April 15.

Season one of The Testaments comprises 10 episodes in total and will be broadcast weekly from this point onwards on Wednesdays.

The initial three episodes established the storyline, with the new series taking place four years following the conclusion of The Handmaid's Tale series finale.

The programme followed Agnes MacKenzie (played by Chase Infiniti) as she attended Aunt Lydia's (Ann Dowd) school and readied herself to become a wife, carrying out her marital obligations.

At the same time, Daisy's (Lucy Halliday) heartbreaking backstory was revealed and how she found herself in Gilead, masquerading as a Pearl Girl.

The Testaments is set four years after The Handmaid's Tale concluded and the struggle for Boston.

While the programme functions as an adaptation of Margaret Atwood's 2019 novel The Testaments, similarly to The Handmaid's Tale sequel there are departures from the original text.

Discussing the new series, The Testaments' showrunner Bruce Miller spoke about adapting the book. He told The Hollywood Reporter: "I'm trying to not necessarily take things in the order they happen in the book, but to take the big central elements and move them into a timeline that makes as much sense as we can."

Miller explained that while they were endeavouring to follow the "overall story of the book", the "ins and outs" of the storyline needed to differ because the characters were of different ages - The Testaments novel is set 15 years after The Handmaid's Tale.

This means that, crucially, the character of Daisy will differ between the television series and the source material.

Miller stated: "Holly would only be four or five. So in our story, because of the timeline, baby Holly, as far as we know, is safe growing up in Toronto... for now!"
