Jip-gil and Yeong-pal were classmates at university and are also brothers-in-law. Yeong-pal is a communist, while Jip-gil, his wife's younger brother, is a second lieutenant in the army. Yeong-pal attempts to bribe Jip-gil, while Jip-gil tries to persuade his brother-in-law to change his ways. Amid this conflict, the Yeosu–Suncheon Rebellion breaks out, and the two men find themselves fatefully pitted against one another.
