Mara, a young technician, secretly removes a tiny energy fragment from her city’s power Core to investigate a strange fluctuation. That night, the entire city loses power, and the fragment in her possession goes dark. With her childhood friend Jonah, she discovers the Core has been emptied and a mysterious glowing boy named Ivo was inside it. Ivo is the true source of the city’s energy, exploited for decades. As corporate forces hunt them, Mara revives the fragment, restoring part of Ivo’s strength. Refusing to return him to captivity, they escape to his cosmic home, freeing him and ending the city’s stolen light.
