Surreal vignettes starring our four-legged friends.

Played on a distant television screen in the dark (with some additional zooms by Lawler), 'Runaway' mainly consists of looped footage of what looks like a Fleischer or Terry cartoon, in which a group of dogs, intrigued by surrounding sounds, run to the left of the screen, and then to the right, back and forth, while a frenzied, spiraling organ score plays over the top. The scene eventually begins to warp and disintegrate. The result is equal parts mind-numbing and hypnotic.
