Yoo Si-jin (Song Joong-ki) is the captain of a South Korean Special Forces unit. He catches a motorcycle thief Kim Gi Beom (Kim Min Seok) with Sergeant Major Seo Dae-young (Jin Goo). The thief is injured during his capture and is sent to the hospital. Dae-young realizes his cellphone was stolen by the thief and goes to the hospital along with Si-jin to retrieve his cellphone. In the emergency room, Si-jin meets Dr. Kang Mo-yeon (Song Hye-kyo) for the first time. He falls in love with her immediately. Mo-yeon mistakenly assumes Si-jin is part of thief's criminal gang due to his nickname "Big Boss", which is actually his callsign. He proves to her that he is a soldier with the help of army doctor Yoon Myeong-joo (Kim Ji-won). Si-jin and Mo-yeon begin to date, but due to their jobs, their dates don't go well. Si-jin takes an order to lead his soldiers on a peacekeeping mission to the fictional country of Uruk. Meanwhile, Mo-yeon is upset because she failed to become a professor due to a colleague's privileged background. When Si-jin and Mo-yeon meet again, they talk about their views on life and realise how different they are. Si-jin, as a soldier, kills to protect lives and Mo-yeon, as a doctor, tries to save lives. They say their goodbyes. Dae-young on the other hand faces a dilemma on whether to continue with his relationship with Myeung-joo or risk being removed from the army by Myeung-joo's father, Lieutenant General Yoon. Eight months later, Mo-yeon rebuffs the sexual advances of hospital chairman Han Suk-won (Tae In-ho) and as a result is assigned to lead a medical team to Uruk. There, Si-jin and Mo-yeon meet and fall in love again. Through their encounters in Uruk-an earthquake and an epidemic-their love for each other grows stronger. While in Uruk, Mo-yeon accidentally confesses her feelings and the two officially start dating, much to the amusement of their respective teams.
