The first two episodes of 10-part first season of The Terror are on BBC2 TV from 9pm on Wednesday March 3.

Faced with sub-zero conditions, limited resources, dwindling hope and fear of the unknown, the crews of HMS Erebus and HMS Terror are pushed to the brink – and no one is coming to save them.

The fate of the real expedition, which set sail in 1845 and led to more than 120 crew members inexplicably disappearing, has warranted a great deal of speculation. After almost 175 years of searching, coincidentally, the ships were discovered by arctic research groups in 2014 and 2016.
