Opilio crab season is about to begin, and the forecast is glacial and dangerous. On a cold, rainy January day when sunlight lasts just six hours. 171 boats begin the journey out of Dutch Harbor, Alaska, sailing up to 450 miles northwest of the small town in search of crab. But shortly after he leaves port, smoke and heat force one captain to surrender valuable time to turn around for repairs, only to discover that an EIRB, or emergency signal, has rung out from a sister boat. Meanwhile, gale warnings buzz over the radio, alerting captains of treacherous ice conditions that, if allowed to build up on the crab pots, could capsize a boat.Finally, at noon, the Opilio crab season begins, and the fleet is forced to put their emotions aside and begin fishing.
