The Dark Lord of the business world, Matty Choi Cheung (played by 黄子华), caused his mentor to commit suicide and thus left the business world in shame. However, upon hearing that his mentor's wife, Clara Ye (played by 李绮红), was now in massive debt, he decided to earn money to pay off her debts by selling "ideas" to businessman Tang Ji (played by 许绍雄). But due to his rebellious personality, he refused to become a salaried employee which led to unstable income. Consequently, he was constantly hounded day and night by debt collector Mimi Lam (played by 佘诗曼). The two engaged in constant scheming and chasing, turning them into an unlikely comedic duo. It wasn't until Choi Cheung met his half-brother Anzu Lian (played by 谢天华) that it triggered painful memories of being abandoned by his mother as a child. Suddenly changing character, he began a murderous rampage against the An family. Even the usually cunning Mimi Lam was at a loss, unable to fathom what exactly Choi Cheung was up to.
