장보고
Jang Bogo (Choi Soo-jong) rises from a lowly slave to the military commander of the sea during the Unified Silla Dynasty. Along the way, he battles pirates, and engages in a heated rivalry with Madam Jami (Chae Shi-ra), a Silla noble who squares off against Jang Bogo for trade rights in the South Sea. Yeom Jang (Song Il-gook), Jang Bogo's charismatic comrade, supports Jang in his ascension to become the "Emperor of the Sea." But Yeom Jang competes with Jang Bogo for the love of Lady Jung-hwa (Soo Ae).
