Given the backdrop of a large-scale war, the stakes are high for everyone in The War Between the Land and the Sea. Actress Jemma Redgrave has hinted that her character, Kate Lethbridge-Stewart, may be in danger, suggesting that no one is truly safe.
The new Doctor Who spin-off features the Homo Aqua, a species rising from the ocean to attack humans. The team at UNIT must quickly find a way to stop them before it’s too late.
The five-episode series, created by Russell T Davies and co-written with Pete McTighe, centers on Barclay Pierre-Dupont (Russell Tovey) and Salt (Gugu Mbatha-Raw) who are leaders of competing groups.

The science fiction drama features Vanessa Redgrave reprising a role she originally played in 2012. She told RadioTimes.com that because the story has such high stakes, the threat of death hangs over all the characters – including her own.
The actor jokingly wondered what the future holds for her character if the show continues. She described playing the role as a wonderful experience, both on Doctor Who and now in this current series, saying each time she’s asked to return feels like a special opportunity and hoping it continues for a long time.

Redgrave hinted at difficult times ahead for Kate, but McTighe, known for her work on shows like Wentworth and Neighbours, revealed that Kate’s character will take a surprising turn in the new spin-off.
He believes that fans of Doctor Who, especially those who are familiar with and love a particular character, will be surprised by the character’s development throughout the series.
Alongside stars like Redgrave, Tovey, and Mbatha-Raw, the cast of The War Between the Land and the Sea also features Alexander Devrient, Ruth Madeley, Adrian Lukis, Vincent Franklin, and Colin McFarlane, who is returning as his character from Torchwood.

A major detail has been revealed: the upcoming spin-off will tie directly into the events of Torchwood‘s third season. The show’s creator suggests that watching both this new series and Children of Earth will create a more complete and enjoyable experience.
Both stories center around encounters between humans and alien life forms, but focus on diplomatic interactions. We’ve reused many of the same sets from Children of Earth – you’ll recognize hallways and staircases – because they take place in the same shared universe.
The War Between the Land and the Sea premieres on BBC One and BBC iPlayer on 7 December.
