Time flies and the world mortals are strangers. Some meet once but stay together for the whole life while some depart forever. A fishing village south of the Yangtze River and a debris flow set free four girls: an ignorant blind girl experienced the great sorrows in the world but never changed her mind; a selfish and beautiful girl got pregnant before marriage three times but was repeatedly abandoned, and finally changed her identity from a mistress to a wife living a secular life; a plain rural girl got pregnant and suddenly died before marriage, leaving her half-mad husband; a stubborn girl like the lady general Hua Mulan never left her sisters and conveyed the true love. They tried love with the strong will and bloomed with beautiful flowers, making the spring river red.
