Ang Babae sa Septic Tank chronicles a day in the life of three ambitious, passionate but misguided filmmakers as they set out to do a quick pre-prod at Starbucks, a courtesy call to their lead actress, Eugene Domingo, and an ocular inspection of their film’s major location, the Payatas dumpsite.
Director Rainier, Producer Bingbong and Production Assistant Jocelyn are well-to-do, well-educated film school graduates who are dead set on making an Oscar worthy film. They believe they have a winning script, the energy and the drive to make their dreams come true. Like most filmmakers they know, they have devised a screenplay that will show the real essence of our culture: poverty. In the course of one day, they brainstorm and exhaust all possible treatment of their project: the story of Mila (Eugene Domingo), a mother from the slums, who out of desperation to survive, has sold her child to a pedophile. As they discuss the possible executions of the story, the movie-within-a-movie gets reborn in Jocelyn’s imagination several times.
