As the co-founder of the Chinese law firm Donald & Co., Charles Cheuk (Lau Dan 劉丹), has been a chairman of its committee for many years. Though he had promised his managing partner KC Lau (Liu Kai-chi) that he would step down, Charles hires the money-minded lawyer Kent Cheung (Alex Fong) as a new partner for the firm, hoping that he would be able to counterbalance KC’s growing obsession for authority.
KC had built up great influence in his years with Donald & Co. His associates include the abled lawyers Duncan Yam (Raymond Cho 曹永廉) and Martha Fong (Mandy Wong 黃智雯). With Patricia Lee (Florence Kwok 郭少芸) and Nick Chau (Matthew Ho 何廣沛) as Kent’s only strongsuits, KC assumed he had the upper edge in their game of power.
However, a traffic accident catches KC off guard, and Kent takes advantage of the situation. He gets himself a lucrative offer from Charles, who promotes Kent to senior partner. During this time, Kent re-encounters assistant solicitor Hazel Cheuk (Ali Lee 李佳芯), and they develop a close mentor-student friendship.
Feeling his power ebbing away, KC becomes a ticking time bomb, ready to explode at any moment. But while fighting for control, a toothless tiger comes out from under the radar, ready to seek revenge.
