“The Rain” (2020) brings the Danish post-apocalyptic series to its final and most emotionally complex chapter. After years of running, hiding, and searching for answers, the surviving characters find themselves confronting not only the deadly virus carried by the rain but also the consequences of their choices and loyalties. The world is still fractured, and humanity is on the brink of extinction, but what truly hangs in the balance is the relationship between two siblings who began this journey together.

Rasmus and Simone, once inseparable, now stand on opposite sides of a conflict that has grown far beyond them. Rasmus, transformed by the virus and convinced of his own power, believes he can build a new world—one stronger, cleaner, and free from human corruption. Influenced by those who see him as a weapon rather than a person, he falls deeper into a vision that teeters between salvation and destruction. Simone, determined to protect what remains of humanity, refuses to accept that her brother is lost.

The season amplifies the tension through a series of dangerous encounters between factions fighting either to control the virus or end it entirely. As Simone joins a group that still believes in rebuilding civilization, she faces the heartbreaking reality that stopping Rasmus may be the only way to save the future. Their emotional struggle gives the series a personal core amidst the chaos of collapsing societies and desperate survival.

Meanwhile, the supporting characters each carry their own arcs that echo the show’s central themes of hope, trauma, and identity. Martin, torn between loyalty to Simone and an understanding of Rasmus’s pain, becomes a tragic symbol of divided allegiance. Fie’s scientific knowledge becomes both an asset and a burden as she races to find a solution that doesn’t come at the cost of innocent lives. Even characters once defined by fear or selfishness begin to evolve as the stakes grow higher.

Visually and tonally, “The Rain” (2020) pushes its world further into darkness. Forests feel emptier, cities are skeletons of their former selves, and every raindrop still carries the weight of death. Yet within that darkness, small rays of hope begin to break through, suggesting that survival is not solely about endurance but about choice.

The climax brings the emotional battle between Rasmus and Simone to its devastating conclusion. Faced with undeniable truth, Rasmus must finally confront what he has become and what he has done. Simone, driven by love rather than vengeance, becomes the anchor that forces him to see humanity again. The series ends with a bittersweet balance of loss and renewal, reminding viewers that even after the storm, the future can still begin with a single act of courage.
