It’s time to journey back to Scandinavia for season 2 of The Rain, Netflix International’s pocket apocalypse series in which rainwater contaminated by a man-made plague virus has killed almost everyone in Denmark. That country, and possibly parts of the countries it borders, have been closed off in a quarantine zone, while the company which created the virus, Apollon, tries to find the cure. The quarantine zone is a post-apocalyptical hellscape, while the rest of the world continues on as if nothing has happened.
Before the end of season 1, our intrepid gang of survivors, Simone, Rasmus, Martin, Lea, Patrick and Jean, discover that, after 6 years, the rain is no longer toxic. But, as was shown in that other famous viral plague series, 28 Days/Weeks Later, viruses have a way of mutating and spreading when they get a sequel. This was set up at the end of season 1, when Simone and the Scooby gang brought Rasmus, the still-infected patient zero, to their father Frederick’s company, Apollon, on the edge of the quarantine zone.
They aren’t at the Apollon compound long before viewers are shown that Frederick’s partner at Apollon, Sten, evil scientist and CEO of the company, intends to use the virus to hold the world hostage. He needs Rasmus alive and still infected in order to enact his plan.
