Lina's signature spell doesn't work, and that one fact shatters everything you thought you knew about how this world operates. The movie trades power scaling for chaos, where an entitled princess and her dragon army are somehow the least ridiculous problem in the room. By the time you realize the actual threat, you're laughing too hard to care that the rules changed.
Lina Inverse and her companion Naga are taking a peaceful lunch break when dragons suddenly descend on the quiet town. Behind the chaos is Marlene Culvert, a spoiled princess waging war against her own father over something as trivial as her allowance. What should be a straightforward monster-slaying job turns complicated when Lina's most powerful spell mysteriously stops working, forcing her to adapt on the fly against Marlene's elite knight squad and endless dragon forces. What starts as a comedic premise quickly spirals into something messier and more dangerous than expected. Lina finds herself outmatched in ways she never anticipated, struggling against an opponent who refuses to play by normal rules. The tone swings between laugh-out-loud absurdity and genuine tension as Lina realizes her usual toolkit won't cut it this time.
