In fighting against the triad illegal activities, police officer Foon (Andy Lau) witnesses numerous brothers turn against one another due to mistrust and suspicion. The old value of "righteousness and brotherhood" in the gangland has long been replaced by profit and money.Separated since a young age at their father's (Wang Zhi-Wen) arrangement, Yiu (Michael Miu) and Shun (Eason Chan) grew up in different places. Years later, Yiu succeeds his father to become the triad boss. His desire to legitimize the illegal dealings within the gang is met with opposition from Kui (Tong Chun-yip) who carries on with the illegal activities secretly. The crisis brings the two brothers back together again. However, a series of setups arranged by Yiu causes Shun to flee to Thailand, accompanied by confidantes Ching (Crystal Huang) and Ghostie (Wong Yat-wah). As Shun is caught between life and death, the trust between the brothers is put to a serious test. When Shun finally realizes the true intention of his brother, things are already beyond repair.
