Su Wan, a gold medal preschool teacher in the 21st century, accidentally touched an old rattle with a strange pattern during an "Reminiscence of Old Objects" activity organized by the kindergarten. When she woke up, she found that she had traveled to the family home of the Northern Military Region in 1976 and became "Su Wan", a timid military wife who had just joined the army and was ostracized by her neighbors because her husband was not at home all year round. The original owner left behind a son, An An, who had just turned four years old and was extremely sensitive and introverted due to lack of care. Her husband, Lu Zhanting, was a young and promising but unsmiling battalion commander in the military region. He was leading the troops to perform tasks on the border and knew very little about the situation at home.
With professional knowledge and love in modern early childhood education, Su Wan not only had to adapt to life in an era of scarce supplies and complex interpersonal relationships, but also carefully played the role of "military wife" and "mother", using her own way to warm the sensitive An An, improve neighborhood relations, and inadvertently bring scientific parenting concepts into this era. When the stern husband Lu Zhanting returns home, facing this familiar yet unfamiliar wife, what kind of sparks will collide between the two? In this era, can Su Wan find his own value and happiness?
