“Fortitude Season 2” returns to the Arctic. For more chills. And thrills.

Remember the parasite threat from season one of Fortitude? It is gone, but the residents are still fleeing the Arctic town in droves. Cut off from the mainland, those who remain in Fortitude battle on. However, in the wilderness, nature is growing restless and unpredictable. When the sky turns red, locals fear it is a bad omen for the town.

Welcome to Public Media Distribution’s Fortitude Season 2 on Blu-ray and DVD. The new series sees Dennis Quaid, Ken Stott Parminder Nagra, Robert Sheehan and Michelle Fairley join its stellar international cast.

Having disappeared after shooting Elena, Sheriff Dan Anderssen (Richard Dormer) is presumed dead. Vincent (Luke Treadaway) remains traumatized by his attack and Hildur (Sofie Grabol) struggles to hold on to her marriage, and her office. Eric (Bjorn Hlynur Haraldsson) fails to step into Dan’s shoes, leaving Ingrid and Petra to police a fragile community. New faces are pulled into Fortitude’s vortex, including Ingrid’s stepfather Michael (Quaid). A fisherman, he is desperate to raise funds to buy treatment for his dying wife, and desperate times call for desperate measures.

At the research center, ambitious newcomer Dr. Surinder Khatri (Nagra) spots an opportunity that encourages her to push both medical and ethical boundaries. Then, a horrendous death rocks Fortitude. What looks like a careless accident involving a snowplow turns out to be a barbaric murder. As the police team investigate, a strange new figure appears hell-bent on destroying an evil spirit he believes has descended upon Fortitude and its inhabitants. There’s a demon amongst the herd and it has to be stopped, no matter what the consequences . . .
