May (Xinchen Xu) and August (Qiu Lier) are a pair of sisters who have a very good relationship. They have lived in a warm family since childhood and have lived a happy life. The arrival of the war shattered the families of the two sisters in an instant. Their father died, and the whole family relied on their strong mother (Ye Tong) to support them. Misfortunes never come alone. August fell ill with a high fever. Her mother risked her life to find medicine on the streets blocked by the Japanese army. Unfortunately, she died. May, who escaped by chance, brought her sister to the refugee camp built by the church. Life in the refugee camp was hard and full of dangers. Finally, May and August looked forward to their relatives. Following their uncle, the two sisters came to Zhenjiang and met Fang Yi (Xue Bin), a boy who had similar experiences with them. Soon, Zhenjiang also fell. Can May and August, who have fallen into desperate situations again and again, escape from danger this time?
