《总统》为家庭剧。讲述了男主人公从最底层通过不断奋斗逐步登上总统宝座的故事。该剧虽说以政治为题材，却与以前的针对韩国现代政治系列剧存在根本差异。主要描述了人权律师出身的总统与其藏匿起来的儿子和好的过程。
Plot Summary:Three months before the presidential nominating convention, Jang Il Joon, from the New Wave Party, declared his candidacy. On that same day, a woman died in a gas explosion in Sam Chuk. Yoo Min Ki, a documentary producer, heard of his mother's sudden death and headed back home. As he cast his mother's ashes in the sea, he thought of his childhood: his father always blurted out that Min Ki was not his son whenever he was drunk. After the funeral, Min Ki returned to Seoul and Jang Il Joon asked Min Ki to work as a PR agent to record the election campaign process. When Min Ki asked Il Joon why he was chosen, Il Joon confessed that Min Ki was his son. Min Ki soon begins to suspect that his mother's death was not an accident and that Il Joon had actually killed her.
