Welcome to Dongmakgol (Korean: 웰컴 투 동막골), also known as Battle Ground 625 (UK), is a 2005 South Korean war comedy-drama film. Based on the same-titled long-running stage play by filmmaker/playwright Jang Jin, Park Kwang-hyun's debut film was a commercial and critical success.

The story is set in Korea during the Korean War in 1950. Soldiers from both the North and South, as well as an American pilot, find themselves in a secluded village, its residents largely unaware of the outside world, including the war.

It was South Korea's official entry for the foreign language film category of the Academy Awards in 2005, and at the time the fourth highest grossing South Korean film of all time.

In September 1950, during the Korean War, U.S. Navy pilot Neil Smith (Steve Taschler) is caught in a mysterious storm of butterflies and crash-lands his plane in a remote and mountainous part of Korea. He is found by villagers from the nearby mountain village of Dongmakgol, who nurse him back to health. Dongmakgol is cut off from the outside world and its inhabitants have no knowledge of modern technology or of the massive conflict raging around them.

Meanwhile, a nearby platoon of North Korean soldiers is ambushed by a South Korean unit, leaving most of the North Koreans dead. Three surviving North Korean soldiers — Rhee Soo-hwa (Jung Jae-young), Jang Young-hee (Im Ha-ryong), and Seo Taek-gi (Ryu Deok-hwan) — manage to escape through a mountain passage and are found by Yeo-il (Kang Hye-jung), an absent-minded girl from Dongmakgol. Yeo-il leads them to the village where, to the North Koreans' alarm, they find two South Korean soldiers, Pyo Hyun-chul (Shin Ha-kyun) and Moon Sang-sang (Seo Jae-kyung), both of whom had deserted their units and had also been led to Dongmakgol by another villager.

The unexpected encounter triggers a Mexican standoff. Initially, the villagers are rounded up between the North and South Koreans, but they slowly drift away to go about their own business as the night passes into morning (being largely unaffected or bemused by the soldiers' actions). During a bout of rain, Yeo-il gleefully pulls out the pin from a grenade held by Taek-gi (mistaking it for a ring), sending the soldiers into further panic.

After an indeterminate amount of time, Taek-gi, worn by fatigue, accidentally drops his (now-armed) grenade; the grenade fails to explode despite initial panic from the soldiers. Believing it to be a dud, Hyun-chul discards the grenade behind him into the village storehouse. It then explodes, incinerating the village's entire stockpile of corn. The remnants fall down from the sky, surrealistically, as popcorn.

The North and South Korean soldiers, realising that their quarrel has condemned the village to starvation in the upcoming winter, reluctantly agree to a truce and divert their efforts to making up for the damage they have caused. Together, they undertake work across the village and help harvest potatoes in the fields. During a day of fieldwork, the soldiers work together to kill a wild boar attacking the villagers, which the apparently-vegetarian villagers then bury without eating, much to the annoyance of the soldiers. That night, the North Korean soldiers, South Korean soldiers and Smith separately sneak out at night to dig up and roast the boar, leading to an unplanned communal meal that loosens the tension between the soldiers.
