An old man and a young man guard the junkyard on the edge of the city. They can accurately estimate the price of a piece of scrap copper, but they cannot calculate the weight of a human heart.
They are forced to walk a tightrope between morality and survival, love and danger. Behind wealth is an invisible network that has already been woven. Some people want to pull them ashore, while others want to drag them into the water.
See how a humble speck of dust flutters and struggles in the wind of the times, and finally grasps its own hotness in the cold reality.
