Young Jiang Wan was expected to get high scores and pursue her studies, but her mother rigged it using two paper balls both written with "Marry", trading her off for a bride price. After marrying into a fishing family, she refuses to bow to fate, using her knowledge to seize opportunities in catching seafood and running a seafood shop, striving to save up for tuition while fighting market injustice. Her husband Cheng Xianghai and mother-in-law Zhao Yulian give her respect and support. She successfully gets into a health school, returns to her hometown after finishing her studies to work as a village health worker, guards the health of the villagers, lets go of past knots, and lives out her own life with her own hands.
