In an abandoned cement yard in the southern suburbs, a group of workers living in a utopian memory plot a “demolition” to make a quick buck. Chen Qing, a young boy among the workers, hopes to use his actions and even sacrifice himself in order to take his uncle away from this place, in order to wake up his young heroic uncle. At night, his relationship with his uncle had become subtly close, rigid, and broken, and his quicksand memory was like this dusty cement factory, eventually buried in dust.
