Overview
- Vigil season 3 premiered on BBC iPlayer and BBC One on 30 August with the first two episodes available to stream from 6am and the first episode broadcast at 9pm that evening.
- The plot follows DCI Amy Silva and DI Kirsten Longacre as they investigate the killing of a covert British special forces member at a remote Arctic research station and try to prevent an international confrontation over Arctic access.
- Production split between Scotland and the Norwegian archipelago of Svalbard, where the crew faced extreme cold that drained camera batteries and required wildlife safety measures such as polar‑bear precautions.
- The new six‑episode run is being released in batches of two episodes per week on BBC iPlayer with BBC One airing each pair across Sunday and Monday nights, and international platforms such as Peacock, Crave and SBS are expected to announce windows after the UK broadcast.
- Creator Tom Edge frames the season around divided loyalties and resource competition, and the show highlights a specific legal quirk of Svalbard’s treaty that allows civilians from many countries to live there while barring military bases, making the location a plausible story setting for rising Arctic tensions.
