The Rig

With Baz missing and presumed dangerous, the crew split into groups to search the production module and find him, and Rose takes the painful decision to isolate Fulmer. But as Rose makes a perplexing breakthrough, the manhunt becomes more frightening and mysterious when the crew are hit by power failures and paranoia, and they discover things that push them far beyond their comfort zone.

Baz and Garrow get closer to understanding their mission when they explore the pump control room, and realise they need Fulmer to help them – leading to painful consequences for Fulmer as he struggles to keep a grip on his sanity. When the crew's anxieties rise as a glimmer of potential hope turns sour, Magnus finds himself losing his grip as tensions amongst the group reach fever pitch.

The new arrivals on board from the Kinloch Charlie immediately make their presence felt, as Pictor head Coake enlists a group to undermine a weakened Magnus and force their way to the pump control. But when Coake's motives are investigated and the crew realise he isn't giving them the full truth, they find themselves locked in an urgent race for answers with lives at stake.

Scores are settled and mysteries revealed as Coake is pushed to explain Pictor's plan and the true reason for his mission onboard, Rose and Fulmer work out the horrifying extent of what the coded messages they have discovered really mean, and Magnus must put his personal demons to rest and lead the crew in one final bid for their survival.
