This documentary recounts a desperate tale of the doomed Franklin expedition and the equally desperate struggle to find out what went wrong. In 1845, Sir John Franklin, with two ships and 132 men, set out to find a route to Asia through the arctic – the fabled Northwest Passage. They never returned. Why the expedition failed became an enduring mystery. After 150 years, Franklin's records are still missing and the search for his ships and the graves of his men continues.
