It's inspired by true events, making it even more gripping viewing.
Is The Terror on BBC 2 based on a true story?
The Terror is based on true events.
The BBC say: "The series is inspired by true events and is a fictionalised account of Captain Sir John Franklin’s lost expedition to the Arctic.
"It follows the Royal Navy’s perilous voyage into unchartered territory as the crew attempts to discover the Northwest Passage.
"Faced with treacherous conditions, limited resources, dwindling hope and fear of the unknown, the crew is pushed to the brink of extinction.
"Frozen, isolated and stuck at the end of the earth, The Terror highlights all that can go wrong when a group of men, desperate to survive, struggle not only with the elements, but with each other."
The real version of events saw Franklin die along with two dozen other men as 129 crew members become icebound. The rest of the men carried onwards, but disappeared.
Many attempts were later made to find the men on those ships with little success.
The two ships used were called HMS Erebus and HMS Terror, which is likely what inspired the name of The Terror.
What is The Terror on BBC 2 about?
The show is described by the BBC as a "horror anthology".
Set in the autumn of 1846, the show begins with two ships getting caught in Arctic ice.
They begin on the Northwest Passage around Canada when trouble strikes.
The show then jumps to spring 1847, then June 1847 and so on as the crews struggle to get out of the ice and survive.
The series imagines what might have happened to the crew as time passes.
