In a quiet, picturesque seaside village, a reclusive 13-year-old girl named Rynn is determined to live independently. She inhabits a solitary house, celebrating a mysterious and apparently solitary existence while ominously concealing where her parents might be. Her routine life starts to attract the attention of suspicious villagers. Among them, the menacing Frank Hallet becomes particularly intrusive, posing a potential threat with his increasingly invasive questions and sinister behavior. Meanwhile, Rynn forms an alliance with a kind-hearted teenage magician named Mario, who becomes her confidant and helper in overcoming various uncertainties.

As the villagers’ curiosity grows, Rynn's efforts to protect her secret become more challenging. The inquisitive landlady Mrs. Hallet and others press her for information. Despite her young age, Rynn exhibits remarkable maturity and resourcefulness, using her wits to navigate dangers and preserve her privacy. However, the true depth of her situation is slowly revealed through interactions that subtly drip-feed hints about her past and the unusual circumstances that govern her present life. Balancing her growing friendship with Mario and fending off probing adults, Rynn's resolve is tested as she strives to maintain control over her life and the dark secrets behind her independence.
