Acting
Suranne Jones does panic attacks so well you'll need a paper bag.
Production
They built a functioning submarine set. The claustrophobia is REAL.
Writing
Tom Edge weaponizes the 'closed circle' mystery format brutally.
Trivia, insights & behind the scenes
The Royal Navy initially refused to cooperate, then changed their minds after reading the scripts. Make of that what you will.
