The work by Sinh, former Deputy Editor-in-Chief of Yen Bai Newspaper, tells about the arduous but heroic struggle of Vietnamese volunteers during the Plain of Jars campaign in Xieng Khoang, Laos, in 1971-1972.

This was a defensive campaign of the Vietnam - Laos coalition army to defeat the plot to invade Laos of Lao right-wing forces and the Thai army during the rainy season, and to protect the liberated area of the Plain of Jars in Xieng Khouang.

The main characters - Thanh Binh, Yen Hoang, Minh Phu and Duong Minh – are classmates. In their 20s, they became Vietnamese volunteer soldiers who performed international missions in the neighbouring country.

The young soldiers braved many hardships and the fierceness of bombs and shells, fought bravely and won the victory. Many of them laid down their lives in the Plain of Jars when they were very young.
