A woman named Mitsuki Murase, afraid her husband will discover her unfaithfulness, is attacked on the road by a white van. The driver, none other than Rohan himself, tries to warn her that a prominent climate activist is hiding in her car, using her as transportation for a terrorist plot. The ensuing crash leaves Rohan nearly immobilized, forcing him to choose between the eco-terrorist's noble goal and the well-being of his hometown.
