Merus Breach is a short science-fiction film that explores an alternative future where mankind has developed Merus-H4, a sound-based technology to clean the heavily polluted air and water. Undetectable by most, the frequency is only audible to a small population of humans, comprising mostly of musicians and performers, who are debilitated by the sound. As a result, these 'Sensitives' are isolated from society in filtered government housing. Merus Breach tells the story of former opera diva Drae Wrathorpe, as she recovers from a breach in the filtering system.
