In the bohemian shadows of Belle Époque Paris, starving young composer Erik Satie longs to overthrow a 300-year musical monarchy. Expelled from the Conservatoire for his unconventional approach, the frustrated cabaret pianist vows to prove his critics wrong. He finds a kindred spirit in the also floundering Claude Debussy. The duo launches a radical crusade against the entrenched musical order. Enduring ridicule, exclusion from venues, and personal demons, they pioneer an art form steeped in the green haze of Absinthe and mysticism. Yet, success begets envy, corroding their once-unbreakable bond. When Satie suspects Debussy of plagiarism, their one-time alliance morphs into a high-stakes rivalry, with a new generation of musicians picking sides. Amidst Satie's struggles to compose a timeless opus in the shadows of despair, the tale unfolds against the backdrop of an ever-changing era, the Dreyfus Affair, and the ravages of WWI. Will their legacies echo through time, or be swallowed by the abyss of forgotten brilliance?
