In 1996, a band of British Hong Kong soldiers who are not granted British citizenship choose different paths after the disbandment of the Hong Kong Military Service Corps. Kwan Chiu convinces Winston to speculate on the stock markets, but the 1997 Asian financial crisis sees Winston lose all his wealth. After a debt-stricken Winston commits suicide, his ex-brothers-in-arms blame Kwan and cut ties with him, but Kwan secretly takes on his debt in place of his widow.

Kwan has joined the triads in the subsequent years. In 2019, Kwan brokers a deal between Taiwanese turtle smuggler Pickle and local triad leader Big Mouth Tai. One day, a young South Asian thief, Mani, is pursued by Tai's top follower Chook and takes shelter in Kwan's home in Chungking Mansions. Mani offers Kwan HK$1 million to take him in for five days to which Kwan agrees. The two men are initially cold towards each other, but start to bond when Mani discovers a video of Kwan's past military services and Kwan takes care of Mani's brother Mansu on his behalf.

Later, Tai finds out that the turtles he bought are dead in transit, summons Kwan to demand the return of the deposit and kills Pickle. Kwan is shocked at seeing the corpse of Mani's cousin Kapil, who was punished for stealing Tai's drugs. Mani gives Kwan a bag of drugs for him to pay off the debt, and Kwan gives him a pack of his hand rolled cigarette as a sign of their friendship. Just as the problem seems to have resolved, Mani is abducted by Tai's underlings, and his relation with Kwan is revealed by Kwan's iconic cigarette.

Pickle's fellow smuggler Bamboo tracks down Kwan, and Kwan leads Bamboo to Tai's hideout, where Mani is held captive. Held at gunpoint, Tai shifts the blame on a seriously injured Chook and seals a new deal with Bamboo. Kwan ferociously fights off a couple of Tai's henchmen, but when Tai is about to deal a fatal blow to Kwan, the betrayed Chook interrupts and kills Tai. Mani rolls a cigarette for a dying Kwan, becoming the first person to do so.

Some time later, Mani gives Kwan's fellow soldiers a note of full repayment of Winston's debt.
