A young, aspiring musician named Jon, struggling to find inspiration, stumbles upon an avant-garde pop band led by the enigmatic and charismatic Frank, a musical genius who always wears a large papier-mâché head. Intrigued by their unconventional sound and Frank's magnetic presence, Jon eagerly joins the band and ventures with them to a secluded cabin in the Irish countryside to record their debut album. As Jon becomes more ingrained in the group's dynamic, he attempts to document their creative process through social media and plans to catapult them to mainstream success.

Tensions within the band rise as Jon's ambitions clash with Frank's vision and the eccentric tendencies of the other members, particularly Clara, who fiercely protects Frank's unorthodox artistry. Amidst the chaos, Jon's obsession with fame and validation tests the bonds within the group and pushes Frank's sanity to its limits. As creative pressures mount and personal conflicts escalate, the journey leads to an intense and poignant exploration of artistic authenticity, mental health, and the true cost of chasing one's dreams.
