A widow who was kicked out by her husband's family accidentally obtained a crack in time and space - she could travel to any corner of the 21st century at any time. She supported her three daughters by picking up "garbage", from a leaky adobe house to building the first new tile-roofed house in the village; from a "broom star" who was stabbed in the spine, to a leader who led all the women in the village to make a breakthrough. Twenty years later, one of the three girls became a teacher, one a doctor, and one a boss. The man who kicked her out of the house came to her with a wine glass and said: "Sister-in-law, I can't help you."
