As violence sweeps the city, a couple escape to an isolated Nordic research facility. On the brink of discovering a cure for the devastating disease, cracks in their marriage start to appear. The outside world grows increasingly hostile and the couple are forced to choose between conflicting allegiances. As they battle for power and truth, the future of the human race is at stake. Suffused with Norse mythology, Paul Murphy's play Valhalla depicts a world where the boundaries of scientific research and the endurance of human love are stretched to their limits. It was joint winner of the inaugural Theatre503 Playwriting Award, and premiered at Theatre503, London, in 2015.
