A high-budget war epic, Road Number One commemorates the sixty years that have passed since the Korean War. It’s based around the historical Route 1, a national highway that served as the main passageway between North and South Korea during the outbreak of the Korean War in 1950. Lee Jang Woo, the son of a poor peasant, has been in love with his master’s daughter, Soo Yeon, since childhood. He joins the military in order to put her through medical school and becomes a brilliant officer, leading his men to victory through guerilla warfare. Mistakenly believing that Jang Woo was killed in battle, Soo Yeon becomes engaged to military officer Tae Ho. Jang Woo returns on the eve of their wedding, and the two are briefly, painfully united, but the eruption of war tears them apart once again, forcing him to fight alongside Tae Ho on top of everything. Jang Woo keeps fighting to get back to his love, but the war continues to find new ways to keep them apart. Leading drama stars So Ji Sub and Kim Ha Neul portray star-crossed lovers who are torn apart by war.
