Halloween Horror Story

S1 E4: For the people and polar bears of Churchill, Manitoba, this Halloween is proving to be more frightful than most. For one new mom and her cub, starvation has driven them toward town on a day when most of the residents have taken to the streets. It's up to conservation officers to keep everyone safe, but it won't be easy. A polar bear incident last Halloween has the town on high alert. Making matters worse, an influx of wildlife documentarians has arrived to capture the action during the final weeks of bear season, causing their own kind of trouble.
