Serhiy first laid eyes on Iryna under the swirling lights of the best disco in town. She was wearing a cool jumpsuit with a bright red belt, which drew attention to her waist as she wiggled to the pulsing beat. Serhiy was freshly discharged from the Red Army and was happy to be able to let his hair down. He thought Iryna was beautiful and couldn’t take his eyes off her. He wouldn’t work up the courage to ask Iryna out until a few days later, but once they started dating, Club Edison 2 became a favourite haunt and they looked forward to the weekly discos.

They planned to get married on Saturday 26 April 1986. But the night before the wedding, they felt the ground shake and heard a booming sound. It came from the direction of the nuclear power plant. On the morning of the wedding, as Serhiy went to pick up his best man from the station, he found the streets full of soldiers wearing gas masks and washing the streets down. Rumours swirled that there had been an accident at the Nuclear reactor, but nothing official was said. They called the authorities who told them they must still hold their wedding. As engineers and firefighters battled an unfolding nuclear catastrophe, the city’s residents were told nothing. Iryna and Serhiy married, smiling for photographs, but stumbling during their much practised waltz, as unease rippled through the room. By the end of the wedding reception, the celebration descended into chaos. Still in her wedding dress, Iryna ended up running barefoot through the streets as evacuation orders spread, leaving behind her home, her possessions, and the city where their love had begun.
