On an unknown planet in an uncertain time, a two-tiered society has taken shape. The ruling class live above ground and wear masks on their faces, while the working class labors below the surface of the planet. The lowest order of the underground culture – prisoners, revolutionaries and various troublemakers – are forced to wear boxes locked around their heads. One day, an alien craft crashes on the planet. Gritt (Adom Cooper) and Brythle (Jenny Kim), a pair of rebellious young lovers from the upper tier of the planet's society, discover the wreckage. Unknown to them, the wreckage is a Voyager program space craft that was launched from the U.S. in the 1970s. Within the wreckage is a long-playing gold album featuring rock music of the 1970s. Despite the efforts of the ruling class to destroy this album, the young lovers are able to broadcast the music to the planet's oppressed masses. With this musical discovery, the planet faces a sudden and unstoppable turn of events that brings about the eponymous uprising.
