SPY

Sun Woo, a field agent with the National Intelligence Service, has an accident while on a mission in China.

Ki Chul, Hye Rim's former boss, shows up at her house and threatens to reveal her real identity to the world.

Ki Chul keeps pushing Hye Rim to bring Sun Woo to him, but Hye Rim decides to turn herself in instead.

Sun Woo suggests to Joong Hyuk a double agent operation using Soo Yeon to find the North Korean spies.

Sun Woo is shocked by Soo Yeon's death but tries to save Soo Yeon's family as he had promised her.

Hye Rim suspects that Ki Chul also planted a wiretap at Yun Jin's apartment and sneaks into her apartment.

Yun Jin is distressed over who to choose between her family and Sun Woo after getting her identity revealed.

Hye Rim and Woo Seok invite Sun Woo's colleagues to their house to plant a wiretap on Joong Hyuk's cell phone.

Sun Woo accidentally sees Hye Rim and Ki Chul meet and is shocked that his parents have deceived him.

As Sun Woo begins to dig into the truth about his parents, Ki Chul contacts Sun Woo to meet in person.

Sun Woo decides to do what Ki Chul wants on the condition that Ki Chul leaves his family out of everything.

Being threatened by Tae Sik, Sun Woo ends up stealing the hard disk drive that Joong Hyuk has.

Ki Chul gives Sun Woo the hard disk drive and tells him to decrypt it if he wants to save Hye Rim.

Sun Woo finds a way to save his mother, Hye Rim, and live in South Korea as he and his family used to.

Sun Woo faces the danger of losing Hye Rim and the hard disk drive as his plan does not go as he expected.

Hye Rim and Sun Woo begin their final battle to get Ki Chul and the hard disk drive and save their family.
