## Spoilers
### Plot
Lo Ka Yiu ([Tony Leung Ka-fai](https://www.edgepedia.org/tony-leung-ka-fai)) is a young advertising designer in Hong Kong who, while defending his father from an attack, accidentally shoves a street thug in front of a bus and is sentenced to three years in prison for manslaughter.[3](https://www.rottentomatoes.com/m/prison_on_fire) • [5](https://tv.apple.com/hk/movie/%E7%9B%A3%E7%8D%84%E9%A2%A8%E9%9B%B2/umc.cmc.2z0q01g29n7foc9h3f1aotk4t) In prison his impulsive, straightforward temperament soon offends both the guards and inmates with triad backgrounds, and he is treated as "fresh meat" by the hardened criminals who run things and preyed upon by the sadistic guard Officer "Scarface" Hung (Roy Cheung).[3](https://www.rottentomatoes.com/m/prison_on_fire) • [5](https://tv.apple.com/hk/movie/%E7%9B%A3%E7%8D%84%E9%A2%A8%E9%9B%B2/umc.cmc.2z0q01g29n7foc9h3f1aotk4t)
The veteran inmate Chung Tin Ching (Chow Yun-Fat), who lives by the maxim of enduring provocation to keep the peace, repeatedly advises Yiu on how to survive his sentence and steps in to protect him, and a close friendship develops between the two.[3](https://www.rottentomatoes.com/m/prison_on_fire) • [5](https://tv.apple.com/hk/movie/%E7%9B%A3%E7%8D%84%E9%A2%A8%E9%9B%B2/umc.cmc.2z0q01g29n7foc9h3f1aotk4t) Because he defends Yiu, Ching is drawn again and again into the struggles around him, and he finally makes an enemy of the cunning guard Hung.[5](https://tv.apple.com/hk/movie/%E7%9B%A3%E7%8D%84%E9%A2%A8%E9%9B%B2/umc.cmc.2z0q01g29n7foc9h3f1aotk4t) Hung plays the prison's various gangs against one another, producing infighting and inmate betrayals, and matters come to a head in a prison riot that leaves more than one inmate, and more than one guard, scarred.[6](https://www.lovehkfilm.com/reviews/prison_on_fire.htm)
## Style and social commentary
Unlike Lam's *City on Fire*, which retains genre stylization, *Prison on Fire* dispenses with artifice to give a down-to-earth look at the brutality of prison life; even the fight scenes are choreographed not as kung fu acrobatics but as extended, realistic brawls.[7](https://www.scmp.com/lifestyle/entertainment/article/3325993/how-ringo-lams-prison-fire-films-starring-chow-yun-fat-mix-action-and-social-comment?module=inline&pgtype=article) The screenplay by Nam Yin reportedly drew on his own experiences inside prison, and the story works as a social comment on the harshness of prison life without hammering the point home.[7](https://www.scmp.com/lifestyle/entertainment/article/3325993/how-ringo-lams-prison-fire-films-starring-chow-yun-fat-mix-action-and-social-comment?module=inline&pgtype=article)
The Hong Kong Film Archive describes the film as inverting the conventional opposition of hero and villain by casting the prison guards as the oppressors of downtrodden inmates, with the prison serving as a microcosm of society and the director's humanist concern showing through.[4](https://www.filmarchive.gov.hk/tc/web/hkfa/pe-event-2016-9-1-8.html) The violence is blunt rather than armed: there are no guns or large weapons in the film, but the fights include acts such as Chow Yun-Fat's character biting off an ear.[8](https://hkfilm.net/pof.htm) Most of the action takes place in one large cell block, and the stark, bleak look creates a constant tension that even the large riot scenes and the comic relief cannot break.[8](https://hkfilm.net/pof.htm)
## Music
Lam paid close attention to music in the film: the theme song "友谊之光" (Friendship's Light), together with the prison dance scene, sings sorrow and heroism together.[4](https://www.filmarchive.gov.hk/tc/web/hkfa/pe-event-2016-9-1-8.html) The score is credited to Lowell Lo, and Lo Koon-Ting received a Hong Kong Film Award nomination for Best Original Score for the film.[9](https://www.tvspielfilm.de/kino/filmarchiv/film/prison-on-fire%2C12434598%2CApplicationMovie.html) • [6](https://www.lovehkfilm.com/reviews/prison_on_fire.htm) The song later entered wider Hong Kong public life; during the 2019 unrest it was among the songs played by police at a university siege.[10](https://yule.360.com/detail/4843339)
## Reception and legacy
The film was a box-office success and started a Hong Kong prison-film trend that continued into the 1990s.[4](https://www.filmarchive.gov.hk/tc/web/hkfa/pe-event-2016-9-1-8.html) Lam won Best Director at the Asia-Pacific Film Festival for it, in the same year that his *City on Fire* won him Best Director at the 7th Hong Kong Film Awards.[2](https://www.filmarchive.gov.hk/documents/6.-Research-and-Publication/06-02-Filmmakers-Search/Chinese/Ringo-LAM_c.pdf) On Rotten Tomatoes the film holds a 100% Tomatometer from 5 professional reviews and an 87% Popcornmeter score from more than 1,000 audience ratings; the IMDb user rating is 7.2/10.[3](https://www.rottentomatoes.com/m/prison_on_fire) • [11](https://www.imdb.com/title/tt0093304/ratings/) Critics have singled out Chow Yun-Fat's performance, which moves from comic swagger to gravity, and Roy Cheung's work as the guard.[8](https://hkfilm.net/pof.htm) • [3](https://www.rottentomatoes.com/m/prison_on_fire)
Lam followed the film with *Prison on Fire II* (监狱风云II逃犯) in 1991, which the [South China Morning Post](https://www.edgepedia.org/south-china-morning-post) characterizes as going "all out on the violence" compared with the first film's focus on the harshness of prison life.[2](https://www.filmarchive.gov.hk/documents/6.-Research-and-Publication/06-02-Filmmakers-Search/Chinese/Ringo-LAM_c.pdf) • [7](https://www.scmp.com/lifestyle/entertainment/article/3325993/how-ringo-lams-prison-fire-films-starring-chow-yun-fat-mix-action-and-social-comment?module=inline&pgtype=article) The film's standing has lasted: a 2023 review called it "a true classic of HK action cinema" that has "stood the test of time," and audience reviewers rank it among Ringo Lam's best work.[3](https://www.rottentomatoes.com/m/prison_on_fire)
## Production notes
