The popular OTT series of Vigil Season 3 is produced by World Productions, a subsidiary of ITV Studios that produced Line of Duty. ITV Studios is responsible for international distribution of the show and may distribute it via Peacock in the United States, like other seasons; however, this has not yet been confirmed.
Most of the updates will come from official BBC statements, and no trailers will have been released by early April 2026.
The BBC Media Centre or official social accounts will have updates on the release date, trailers, and other first-look content leading up to the expected air date later this year. BBC iPlayer has previous seasons available for streaming.

Vigil Season 3: Plot details
This 6-episode season takes us to an isolated arctic research facility, where D.C.I. Amy Silva (Suranne Jones), along with D.I. Kirsten Longacre, must investigate the assassination of a soldier from a clandestine British special forces operation. They will have to capture the perpetrator before an international crisis erupts over a "land grab" for W/global commodities due to climate change in the North Pole. The two investigators' professional careers and their relationship will be jeopardized if they fail.
The series continues with its trademark high-tension, high-stakes thriller style that blends aspects of police work, military operations, and international politics - as well as a transition from former submarine and drone/military locations to a completely frozen Arctic.
