Soon Yi (Soo Ae) is a good subservient wife and obedient daughter-in-law who leads a simple, monotonous life in a quite village. Every month at her mother-in-law's insistence, she visits the military base to be with her husband (Uhm Tae Woong) mainly so she could produce a male offspring to continue the family line. But one day during her regular visit, Soon Yi hears shocking news that her husband has suddenly left for Vietnam. While searching for ways to follow him, she meets Jung Man (Jung Jin Young), a sleazy conman who strikes a deal with Soon Yi to take her to Vietnam in exchange for her service as the lead singer of his musical band. But as Soon Yi (now under the stage name of "Sunny") and her entourage soon discover, the reality of entertaining Korean soldiers in the midst of a bloody war turns out to be far more harrowing than they had ever imagined.
