The story kicks off with a desperate all-girl punk rock band named "PussyCake" embarking on a bleak, cross-country tour in a battered van to revive their fading musical careers. Driven by fierce ambition, stubborn resilience, and a deep-seated need for validation, the members—lead singer and fiery frontwoman Joyce, brooding bassist Pat, rebellious guitarist Evie, and easygoing drummer Daisy—push forward despite endless setbacks, broken equipment, and mounting interpersonal tension.Seeking inspiration and a desperately needed gig, they accept a shady, off-the-grid booking in a remote, desolate coastal town known as Puerto Bastión. Upon arrival, the atmosphere shifts drastically from mundane touring fatigue to eerie surrealism. The town is completely devoid of normal human life, shrouded in a sickly green haze, and littered with bizarre, pulsating organic sludge. Unbeknownst to them, the location has been ground zero for a catastrophic
extraterrestrial outbreak. An ancient, parasitic alien entity has invaded the local water supply, rapidly mutating the townspeople into grotesque, bloodthirsty monstrosities driven by primal, hyper-aggressive impulses.Trapped in the desolate venue as night falls, the band realizes they are surrounded. The mutating townsfolk breach the building, forcing the musicians into a desperate, adrenaline-fueled
fight for survival. Utilizing their heavy metal gear, improvised weapons, and unyielding punk attitude, the women transform from a dysfunctional musical group into a lethal, cohesive fighting unit. Throughout the grueling night, old interpersonal grievances surface and are violently resolved in the heat of battle. Evie sacrifices herself in a brutal corridor defense to buy the others time, while Pat and Daisy sustain severe injuries defending their turf.Driven by sheer vengeance and the refusal to die obscurely in a nameless ghost town, Joyce steps up as the ultimate survivor. She orchestrates a daring escape plan, weaponizing the band’s high-voltage amplifiers and feedback loops against the sensitive, audio-reactive alien lifeform. In a chaotic, blood-soaked climax, Joyce detonates the venue's jerry-rigged generator, obliterating the horde and the creeping alien biomass in a magnificent wall of fire and noise. Emerging from the smoldering ruins at dawn, battered, bloodied, and utterly transformed by the harrowing ordeal, Joyce secures the band’s legendary status forever—not through their chart-topping music, but as the sole, ass-kicking survivors of a literal alien apocalypse.
