“The Rig” is a Scottish horror-thriller about a North Sea oil rig cut off from the world by a strange fog. It sounds simple. It doesn’t stay simple.
The premise is classic isolation horror: a crew trapped, a mystery growing around them, and a fog that won’t let anyone through. The show, created by David Macpherson and directed by John Strickland, leans heavily on the sci-fi thriller genre while keeping its setting firmly rooted in the physical, claustrophobic space of the rig itself. What starts as a closed-room mystery opens out into something stranger and more dangerous than anyone expects.

The Fog That Cuts Them Off
The Kinloch Bravo is a working oil rig, and the fog that surrounds it is not natural. It blocks all communication with the mainland, leaving the crew unable to call for help or explain what’s happening to them. Inside the fog, spores are discovered that cause infected crew members to act strangely, showing behavioural changes that unsettle everyone around them.
The show spends its early episodes establishing this setup with care. The rig’s layout, its daily routines, and the small details of life confined to a platform at sea are rendered with a sense of weight. This is a show that understands the dread of being stuck somewhere you can’t leave, even before the monsters arrive.
The Crew Divided
The cast is led by Emily Hampshire as Rose Mason, the oil company representative and scientist who joins the rig as a fresh face. Iain Glen plays Magnus MacMillan, the leader and offshore installation manager of the rig. Martin Compston is Fulmer Hamilton, the radio and communications officer, while Rochenda Sandall plays Cat Braithwaite, the medic on board.
Owen Teale’s Lars Hutton is a veteran of the rig who begins to sow tension and division among the crew. Stuart McQuarrie is Colin Murchison, the cook, and Molly Vevers plays Heather Shaw. The ensemble is large, and the show manages to keep each character distinct even as the pressure builds.

The Parasite From Below
The show’s central threat is not human. After examining the spores, a scientist on board suspects that an ancient parasite has been unleashed from the ocean floor. This reveal shifts the story from a tense, slow-burn mystery into something far more threatening.
The parasite idea is where the show stretches its legs and reaches for something genuinely unnerving. The fog isn’t just a tool for cutting off communication; it’s a living thing, and the spores are its way of spreading. That’s a clever twist, and it pays off in the second season.
Season One’s Pace
The first season, released on 6 January 2023, runs six episodes. It moves slowly at times, building atmosphere over character and incident. The fog is the real antagonist in the first half, and the show earns the tension by letting the audience sit with the fear of isolation before the creature shows itself.
The pacing could be tighter. Some middle episodes feel like padding, with the fog and the spores doing most of the heavy lifting while the human drama stalls. But the show’s commitment to its setting keeps the slow stretches from feeling wasted.
Renewal and Expansion
In February 2023, the show was renewed for a second season, which premiered on 2 January 2025. The second season adds new faces to the mix, including Alice Krige as Morgan Lennox, the CEO of Pictor, the company behind the rig. Nikhil Parmar’s Harish is introduced as a survivor from Kinloch Charlie, and the show expands its scope from the rig itself to the broader operations of the company.
The renewal was announced quickly after the first season, and the second season kept the core cast intact while bringing in new threats and new locations. The show’s decision to film entirely in Scotland, making it the first Amazon Original shot entirely there, gives the series a distinct visual identity that sets it apart from other horror-thrillers.
Final Word
“The Rig” is a solid, often tense entry in the horror-thriller field. It doesn’t reinvent the wheel, but it executes its setup with discipline and a strong sense of place. The fog, the spores, and the parasite underneath the water all contribute to a genuinely unsettling atmosphere.
The pacing drags in spots, and the first season’s middle episodes could have been sharper. But the core idea is strong, and the second season’s expansion brings fresh energy to the story.
