There have been countless arctic expeditions featured on the channel. They all generally start with grand ambitions, bold proclamations, and then, inevitably, disaster. Time and time again, ships have vanished into the ice, resulting in the loss of some or all of the crew. But this story is different. This wasn’t an expedition that ended in total ruin. There was no catastrophic sinking, no mass starvation. And yet—something happened on this journey that would remain buried for over a century. A secret so disturbing that when it was finally uncovered in the last 50 years, it completely rewrote the history of the expedition. This wasn’t just an Arctic mission gone wrong. It was something far more sinister. As always, viewer discretion is advised.
