In cooperation with the Commission on Filipino Language (KWF) and the indigenous people of Aeta Magbukun, "Magbukun" is a short documentary on the dying language of the ethnic tribe and the establishment of the first language revitalization program in the Philippines. It features two stories: Alfie Sison, a native Aeta teacher in Bangkal, Bataan; and the Bahay Wika program, a beta project initiated by KWF in partnership with local tribes of the country in preserving native languages.
