Giant

The plot revolves around the lives of the three Lee children: Kang-mo, Sung-mo, and Mi-joo. Their father was killed by Hwang Tae-seob and Jo Pil-yeon, and their mother died in an accident. As a result, the children were separated. Kang-mo and Sung-mo were raised by their father's killers: Kang-mo helped Hwang Tae-seob avoid bankruptcy by advocating the use of a different landfill material, and was later adopted by Tae-seob, and Sung-mo was raised by Jo Pil-yeon, who is a KCIA official. After growing up and knowing the truth, the brothers set off on a quest for revenge. Mi-joo and Jo Pil-yeon's son, Min-woo, fall in love but cannot be allowed together because their families are enemies. Mi-joo becomes pregnant and goes into hiding while Min-woo desperately searches for her. The whole series revolves around the brothers trying to bring down Jo Pil-yeon, who is also cunning and slippery in his political tactics. Later, Sung-mo is shot in the head by an agent of Jo Pil-yeon. Miraculously, he survived, and had to hide from the KCIA. Jo Pil-yeon tries to work in the government by making false papers. Kang-mo finds out that Sung-mo has knowledge of the contents of the real papers, and finds him. They release the papers, and Jo Pil-yeon fails his objective. He runs away, but is later found and arrested. Sung-mo undergoes surgery to take the bullet out of his head, but tragically dies. Many years later, a now-insane Jo Pil-yeon breaks out of prison to try to murder Kang-mo, but fails, and he commits suicide afterwards. The last scene shows Kang-mo receiving word from his wife Hwang Jung-yeon (Hwang Tae-seob's daughter) that his long-lost brother (a fourth sibling who was adopted by an American couple many years ago) has come to visit him. [About] Giant is a 2010 South Korean television series starring Lee Beom-soo, Park Jin-hee, Joo Sang-wook, Hwang Jung-eum, Park Sang-min, and Jeong Bo-seok.
