'The War Between Land And Sea' Season 1, Episode 3: 'The Deep' – A Critical Review
The British science fiction miniseries, 'The War Between the Land and the Sea,' continues its compelling narrative with Season 1, Episode 3, titled 'The Deep.' This installment, part of the expansive Whoniverse, premiered on December 14, 2025, in the UK on BBC One and BBC iPlayer. International audiences can anticipate its release on Disney+ in 2026.
Directed by Dylan Holmes Williams, 'The War Between the Land and the Sea' features a notable ensemble cast. Russell Tovey leads as Barclay, with Gugu Mbatha-Raw portraying the enigmatic Salt. Jemma Redgrave reprises her role as UNIT head Kate Lethbridge-Stewart, alongside Alexander Devrient as Colonel Ibrahim, Colin McFarlane as General Austin Pierce, and Ruth Madeley as Shirley Ann Bingham. Additional cast members include Adrian Lukis, Vincent Franklin, Francesca Corney, Mei Mac, Waleed Hammad, Hannah Donaldson, and Ann Akinjirin.
The series centers on the Unified Intelligence Taskforce (UNIT) as it grapples with a global crisis following the dramatic emergence of the Homo Aqua, an ancient aquatic species also known as the Sea Devils. These beings, long-dormant, resurface to challenge humanity, citing environmental degradation as a catalyst for their actions. Barclay, a low-level UNIT staff member, finds himself unexpectedly thrust into the role of humanity's ambassador, engaging in complex diplomacy with Salt, the Homo Aqua representative. The narrative consistently addresses themes of environmental accountability and the intricate challenges of interspecies relations.
In 'The Deep,' the plot intensifies as Barclay undertakes a perilous journey into the realm of the Homo Aqua. Simultaneously, on land, Kate Lethbridge-Stewart faces mounting pressure as Downing Street and the military engage in covert strategies to influence the ongoing conflict. This episode promises to advance the high-stakes confrontation between humanity and the aquatic species, further complicating the diplomatic efforts and raising the personal stakes for its central characters.
