During the reign of the Empire, two sisters, Koten and Tichina, are the last of their kind after the Empire conquered their planet and committed genocide on their species. Their mother, a Force-sensitive, led a failed rebellion against the Empire, who have created a factory that took their clean water; she was killed in the resulting conflict, and the factory has since caused severe light pollution as well as water pollution for the sea. While Tichina is convinced that they can defeat them with the Force, the elder and jaded Koten is solely focused on keeping them both alive. After they run out of water, Koten is forced to sneak into the factory to take water from the factory's water purifiers. However, Tichina follows her inside and gets spotted by the Stormtroopers. Exposed, Koten and Tichina attempt to flee, but Tichina runs back inside, intending to destroy the primary water tank with the Force and with it the base. Subsequently caught, she is nearly executed, but Koten awakens her own Force abilities to save her sister and together, they destroy the factory and flood everyone within. As the sisters happily embrace, they see that life is returning to the planet and their mother, who they believe is a star, looks down on them.
