Vigil is a murder mystery/political thriller set in the depths of British waters, particularly in the nuclear-powered missile submarine HMS Vigil. When a navy officer dies and a fishing trawler disappears at the same time and place, Detective Chief Inspector Amy Silva (Suranne Jones) is sent in to investigate the case.

While Vigil mostly dove under the radar when it first came out last year, the BBC production is drawing in new audiences as it streams on Peacock. Watching it, it’s easy to forget that this isn’t a box-office production, because it looks and sounds every bit like one. It’s got a massive budget, an epic scale, a thrilling political premise, and talented actors across the board—what’s not to love?
