Lars Erickssong and Sigrit Eríksdóttir form Fire Saga, an idiosyncratic Icelandic musical duo whose lifelong dream is to win the prestigious
Eurovision Song Contest. Lars is driven by an obsessive need to prove his worth to his stern, disapproving father, Erick, while the ethereal Sigrit is secretly motivated by her deep, unrequited romantic love for Lars. Despite being local laughingstocks in their
fishing village, the pair receive an improbable chance to represent their country when they are accidentally selected as contestants through a rigged national preliminary voting process.Upon arriving in Edinburgh, Scotland, for the grand competition, Fire Saga feels drastically out of place amidst the glitz, high-production value, and hyper-sexualized performances of rival acts. They clash with the arrogant, charismatic, and seemingly immortal Russian frontrunner, Alexander Lemtov, who takes a surprisingly protective interest in Sigrit. During a lavish yacht party hosted by Alexander, Lars experiences an intense bout of jealousy and inadequacy. Feeling rejected and alienated by Sigrit, who is pursued by Alexander, Lars walks away from the group.As the semi-finals arrive, Fire Saga’s performance is plagued by chaotic mishaps. Lars, distracted and emotionally wounded, makes a massive blunder on stage that results in a catastrophic mechanical failure and the tragic death of several other contestants in a massive pyrotechnic explosion. Overwhelmed by grief, guilt, and public mockery, a humiliated Lars quits the band and returns home to Iceland to resume working as a humble fisherman, abandoning his musical ambitions entirely.Meanwhile, Sigrit presses forward into the grand finals, supported by Alexander, who realizes she truly loves Lars and gently steps aside. Back in Iceland, Lars experiences a moment of clarity and recognizes that his music is intrinsically tied to Sigrit, and that his obsession with winning was blinding him to the genuine love of his closest companion and his community.Lars rushes back to Edinburgh just in time, arriving at the arena moments before Fire Saga’s scheduled grand finale performance. Instead of playing their assigned, overly commercial track, Lars and Sigrit decide to perform from the heart. They break the contest's rigid rules by playing a deeply authentic, traditional Icelandic ballad, winning over the live audience and viewers worldwide. Although they are disqualified for breaking the rules, they achieve ultimate emotional fulfillment. Lars and Sigrit finally embrace their mutual romantic feelings, returning to Iceland not as champions of a trophy, but as proud, validated artists and partners ready to face their future together.
