In a fishing town that has been polluted by a thermoelectric plant, Mecha is the lingering soul of an environmental activist that died in suspicious circumstances. Her death causes a commotion in the town and leads to mixed feelings within her family.

While her parents Alicia and Nicanor discuss whether to seek justice, Mecha’s oldest son, Juan, is conflicted by the resentment he holds toward his dead mother. This leads Mecha’s ghost to seek reconciliation with Juan, so that he can take responsibility for her memory.
