The War Between the Land and the Sea Episode 5 Release Date
Episode 5 is the finale of The War Between the Land and the Sea. In the UK it is scheduled for Sunday 21 December 2025 around 8 PM on BBC One with the same time availability on BBC iPlayer.
The episode title is The End of the War which fits its role as the closing chapter of this five part story.
This date follows the pattern of weekly Sunday drops that started with the double premiere on 7 December and the next pair on 14 December.
The War Between the Land and the Sea Episode 5 Where to Watch?
In the UK you can watch episode 5 live on BBC One or stream it on BBC iPlayer once it goes up. BBC iPlayer carries the whole miniseries so you can catch up with episodes 1 to 4 before the finale.
Outside the UK the rights sit with Disney Plus as part of the wider Doctor Who deal though the international streaming launch is planned for 2026 instead of a day and date release.
Some guides suggest using a VPN to access BBC iPlayer from abroad but this goes against the service terms so it is better to wait for the official Disney Plus release in your region.
What to Expect from The War Between the Land and the Sea Episode 5?
The show focuses on UNIT dealing with Homo Aqua which is a reimagined form of the classic Sea Devils who rise from the oceans after decades of human damage to the seas.
Across the first four episodes the scale has grown from first contact to outright conflict so episode 5 is set up as the point where the war between land and sea reaches its peak.
The official synopsis hints that Barclay faces a final choice with Salt while UNIT stands on the brink of losing control as the oceans become the main battlefield.
Expect a mix of political tension large scale action and moral fallout rather than a simple happy ending since the series leans into climate themes and hard decisions.
