An analogy between the modern human being, living in mass cities, and the phenomenon of the circle of death - observed in nature with ants who are separated from the main foraging party and lose the pheromone track. They begin to follow one another, forming a continuously rotating circle, commonly known as a "death spiral" because the ants might eventually die of exhaustion. Shot in Mexico City, this vibrant and impressive city is a protagonist, symbolizing a life in endless high speed movement and the humans who are dedicating their lives to endless movement, self-exhaustion in a modern capitalistic based world.
