Mighty Ships - Season 1 Episode 4

No Mighty Ship faces more challenging missions than icebreaker CCGS Henry Larsen. She patrols the rugged North Atlantic, smashing through ten-foot thick frozen slabs, rescuing ice-imprisoned vessels, and keeping remote islands linked to the outside world. This winter, she'll be pushed to the limit when a major winter storm wreaks havoc on the Newfoundland area. Its small coastal communities are counting on Henry Larsen, and her support helicopter, to save them from imminent isolation.
