It's Sunday, September 30, 2018. During the afternoon, light rain has set in over the Argentine capital, Buenos Aires. Not that anyone at the Estadio Malvinas would know it, though. Throughout the day, the crew is working intensively on the stage structure in the huge hall. Meanwhile, in the catacombs under the arena, the band prepares for their performance in the evening. It's not just any band and it's not just any gig. In a few hours, NIGHTWISH will unleash their furious and unique "Decades" showcase on the stage of the Argentine metropolis, delighting thousands of fans. This can be seen on stage in Buenos Aires, where NIGHTWISH start the action with 'End Of All Hope' and lead the us into the night with the epochal 'Ghost Love Score'. In between we experience Finnish bombastic brilliance in its purest form. 'Wish I Had An Angel', 'Sacrament Of Wilderness', 'Elvenpath', 'Devil & The Deep Dark Ocean', 'Dead Boy's Poem' ... goose bumps, moving images, epic sound, preserved for eternity with 19 cameras , Anyone who knows NIGHTWISH knows why this film is essential. And anyone who hasn't seen them will be wondering why they haven't!
