In a dystopian Philippines devastated by environmental collapse, people breathe through a bio-helmet, an oxygen concentrator that extracts air from plants. A young man embarks on a journey to reach the boundary wall between his barren hometown and the neo-Metro Manila — a place still rumored to lead to a better life. Ignoring the beliefs and disagreements from others, his desperation for a more comfortable life drives him forward. With a firm resolve, he climbs ahead, not knowing what lies beyond the wall but firmly believing it holds the promise of a better life.
