A modern female president of renewable resources, Su Min, transmigrates into the 1980s into a mad woman with the same name. Faced with a room full of wine bottles, overdue rent, and an 11-year-old daughter who supports her by picking up trash, she relies on her sorting skills and industry knowledge from her previous life. She earns her first pot of gold by sorting empty wine bottles, then opens Minzi Recycling Station. She deals with threats like extortion from her ex-husband and harassment from local thugs. Step by step, she expands from a tin shop on West Street to a county-wide unified supply center. Finally, she moves with her daughter into a school-district apartment in the city. She turns the "mad woman" into the respectable Boss Su.
