In the 1950s, Chau, along with his partners Fung and Chung, are a formidable team of triad contract killers who successfully wipe out a gang of rival thugs at the fruit market. As time passes, the team has already retired, and Chau is working as a chef in a noodle shop. However, his boss fires him after purchasing a robot to replace his job.
Chau is approached by Fung, who invites him to meet up with her and Chung. Over the years, Fung has amassed a sizable fortune working as a lounge singer and operator of a popular cabaret but has a falling out with her son after he demands she sell her home and business to finance the purchase of a mansion in the prestigious Kowloon Tong district so he can put her grandson in a prestigious school. Chung, an unemployed deliveryman, has fallen in love with a young prostitute named Ching Ching. At Fung's suggestion, Chau and Chung agree to come out of retirement.
The team soon receives a new contract, but when Chau arrives, he finds the client is an old man who hires him to euthanize his terminally ill wife to end her suffering. Chau refuses, but that night, he sees on the news that the old man has murdered his wife himself and is arrested by the police. Sympathetic to the suffering elderly, Chau proposes to his partners that they provide euthanasia services, and the team soon rebrands themselves as "Elderly's Angels".
In one contract, Chau arrives to find only an orphaned young girl named Tsz-ying, who reveals she is the client. Chau is dissatisfied with her request, as his services were intended for the elderly, and when Tsz-ying tries to live stream her euthanasia process, Chau furiously grabs her phone and leaves. Tsz-ying then tails Chau home with her phone's GPS function and asks him to train her as a killer. Over time, Chau relents, realizing they are both lonely and seeking familial warmth. Meanwhile, Fung is forcibly institutionalized after her son forges her signature on documents selling her property. Chung proposes to marry Ching Ching, but she rejects him as being too old for her. Shocked, Chung has a heart attack and winds up in the hospital.
Chau convinces his partners to kidnap Tsz-ying's ex-boyfriend Bun, a gangster who impregnated and then abandoned her, and forces Bun to promise to take care of the baby. After releasing Bun, Fung returns to the nursing home of her own will, while Chung sells his van after learning Ching Ching is getting married in Macau and gives the money to her as a blessing. Chau is then ambushed by Bun's gang, managing to fight them off. Realizing that Bun has lied about his repentance and has pressured Tsz-ying into having an abortion, Chau contacts Fung for help. They manage to rescue her from an underground abortion clinic, but when they try to fight their way out, they run into the police. Chung sacrifices himself to pin down the policemen, allowing Chau to reunite with Tsz-ying.
At the end, Chau visits Chung in prison, who is content with no longer having to worry about money and medical attention. Fung continues to perform as a singer in the elderly home, and Tsz-ying gives birth to the baby, which she raises together with Chau.
