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 the thief's criminal gang, due to his nickname "Big Boss", which is actually his call sign. He proves to her that he is a soldier with the help of army surgeon Yoon Myeong-ju (Kim Ji-won).

Si-jin and Mo-yeon begin to date, but due to their jobs, their dates don't go well. Si-jin receives orders to lead his soldiers on a peacekeeping mission in 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 realize how different they are. Si-jin, as a soldier, kills to protect lives and Mo-yeon, as a doctor honoring the Hippocratic Oath, 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 Myeong-ju or risk being removed from the army by Myeong-ju's father, Lieutenant General Yoon Gil-joon (Kang Shin-il). 

Eight months later, Mo-yeon rebuffs the sexual advances of hospital director 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 (much to the amusement of their respective teams) and the two officially start dating. 

Back in Korea, the two of them continue their dates until Si-jin and Dae-young are sent on an operation in which they disappear and are assumed to be dead. Months pass, and Mo-yeon mourns his death, deciding to commemorate his passing with a volunteer trip to Albania. This is where Si-jin eventually finds her after he and Dae-young are rescued from captivity by "a friend from afar", a soldier from North Korea whom Si-jin had helped save earlier. Si-jin and Mo-yeon are happily reunited. 

In the credits, the entire team is once again called into action following a volcanic eruption in Canada.

Cast

Song Joong-ki as Captain Yoo Si Jin (aka Big Boss) 
The team leader of Alpha Team, an elite special forces unit in South Korea. He is a soldier from a family with a military background. He highly respects his father, who is honourably discharged as a Sergeant Major. He possesses both academic and physical abilities, thus making him a complete soldier. He graduated from the Korea Military Academy and is currently a Captain in the army. His belief that beautiful women, the elderly and children deserve to be protected, his courage to intervene when high schoolers smoke on the streets, and his common sense that wrong is wrong despite having a gun pointed at his head are all part of Si-jin's love for country and a soldier's honour. He is an easy-going, lively character who is confident and at times witty and likes to joke around, depending on the situation. He was later promoted to Major.

Song Hye-kyo as Doctor Kang Mo Yeon (aka Beauty)
A cardiothoracic specialist who works at Haesung Hospital. She is portrayed as an assertive woman who has great abilities but would rather confine herself to the operating theatre. She believes that competence overrules connections but is hit by the harsh reality that she cannot go anywhere without any connections. She is a woman with principles and doesn't fall prey easily to her emotions. Overall, she is the complete package - her speaking abilities are unrivaled, and she is not afraid to admit her mistakes.

Jin Goo as Master Sergeant Seo Dae Young (aka Wolf)
A soldier down to the core - even when he is not working it is as if he is wearing the clothes of a soldier rather than those of a civilian. His heart moves at the thought that he is protecting his family and his homeland with his own two hands. He has experience in dealing with disasters. Since heavy actions are more comfortable for him than lighthearted conversations, he has a hard time expressing himself freely. However, within the shell of this hardcore soldier is a good heart that is deeper than anyone else's.

Kim Ji Won as First Lieutenant Yoon Myung Ju
A terrific soldier who has eyes for only one man. She is not only a soldier but an army surgeon and an orthopedic specialist. She is also the daughter of Lieutenant General Yoon, commander of the South Korean Special Forces Brigade. She follows her father's footsteps and graduates from the Korea Military Academy before doing an internship at Haesung Hospital with Mo Yeon. At her first assignment she meets Dae-young, a sergeant with a GED background. For the first time, she regrets being a soldier but refuses to back down. She is truthful with her feelings, and in order to protect her love she is willing to endure any danger and face everything straight on.
