In 2010, Cheuk Hoi (Michael Miu) secretly travels to Bangkok to conduct a drug operation with his undercover agents in Thailand. Despite the success of the mission, all of Cheuk Hoi's undercover agents are killed in a sea of fire. Back in Hong Kong, Cheuk Hoi's good friend CIB Inspector Lai Sui Kuen (Eddie Cheung), is killed by masked gunmen, leaving Cheuk Hoi to take charge of Cheng Suk Mui (Priscilla Wong) who is not yet officially an undercover. Cheuk Hoi knows that Lai Sir still has undercover agents whose identities have been deleted. To learn the truth about Lai Sir's death, Cheuk Hoi works with Cheng Suk Mui to find and secure the remaining of his late-friend's undercover agents while dealing with corrupt officials in the Hong Kong Police Force. Meanwhile, Chum Foon Hei (Benz Hui) swears to avenge the death of his wife and goes head to head with Victor Ngai (Moses Chan), the leader of the Cheung Heung triad.
