Mary Ellen Bute's first color film tells a story in abstraction of an orange/red triangle imprisioned behind a grid of vertical and horizontal lines uner a sky-blue expanse, perhaps representing freedom. J.S Bach's Toccata (in D Minor) adds dramatic tension to the visual variable in motion. -Cecile Starr

The film's soundtrack is an original musical composition produced with synthetic sound - through photographing unusual geometric shapes and running them through an optical sound head. The images are an artistic rendering of this soundtrack.

Abstract animation illustrates Edwin Gerschefski's modernist composition. Two dots - one blue and one orange - appear most often, sometimes large, sometimes small, sometimes overlapping. When the sounds become more staccato, so do the images: wavy lines become squiggles, short nail-like lines go across the screen in rows. The result is a visual representation of abstract music, lively and spirited in spite of its link to a dance composed to sweat out the poisons of a spider bite.
