A struggling botanist confronts her mother's death after taking in an enigmatic teenager.

Ada is a spirited, seventeen-year-old teenager who dreams of becoming a botanist to help out her single mother, Mirren. For the pair, it truly feels like it's them against the world, especially because Ada's mother has one, huge secret: she is half-plant and half-human, who has the ability to grow a garden from her skeleton. However, Mirren undergoes daily, debilitating chronic pain that prevents her from leaving the house, which Ada tries her best to help her mother through. One day, Mirren suddenly dies, and Ada's life becomes completely undone. Now alone, the once bubbly, outgoing teenager slowly grows into a jaded, bitter adult that isolates herself from the world. Seven years later, while on her way home from work, the now-twenty four year old Ada stumbles upon Wren, a teenage runaway who loves flowers and is haunted by her fraught relationship with her mother. The two quickly form an unexpected bond, and before Ada knows it, she begins to embark on a harrowing journey to reckon with her childhood, and her mother's death, especially when it's revealed that Wren has a few secrets of her own.

Seven years after the mysterious death of her mother, an isolated botanist meets an enigmatic, teenage runaway in a creek. Forming an unexpected bond, the two embark on a harrowing journey to confront their respective pasts, all while slowly realizing that they may not have to face their uncertain futures alone.
