Modern-day best friends Su Tao and Lin Wanqing unexpectedly travel through time together to 1983, where they become a mother and daughter. Lin Wanqing is being mistreated by her husband's family and is forced to leave with nothing. Su Tao awakens a magical storage space, while Lin Wanqing gains the ability to return to the modern era periodically. The two decisively divorce and establish separate households, freeing themselves from their dreadful in-laws. Taking advantage of their ability to travel between eras, they trade goods and start a business to make a living. Along the way, they overcome one crisis after another, work hard to build a better life in the 1980s, and use their own hands to create a brand-new future.
