## Spoilers
### Plot
Lee Chung-chi (Louis Koo), a Hong Kong police negotiator, learns that his 16-year-old daughter Wing-chi (Hanna Chan) has disappeared while traveling in Pattaya, Thailand, and flies there to search for her.[2](https://www.boxofficemojo.com/releasegroup/gr1666863621/) • [10](https://www.fandango.com/paradox-2017-211114/movie-overview) The Chinese-born Thai officer Chui Kit (Wu Yue) allows Lee to join the investigation, and Kit's colleague Tak (Tony Jaa) works alongside them.[11](https://www.gscmovies.com.my/paradox/) A video clip that accidentally captured the daughter's abduction is uploaded to a police website and then mysteriously deleted; when the officers trace the person who posted it, they are ambushed by unidentified men destroying the evidence.[12](https://www.bonafilm.cn/product/64.html)
As the investigation closes in on the culprits, the case proves more complicated than expected: the trail runs through corrupt police, a gangster-connected government aide trafficking in organs, and the surrounding mayoral election, and the mastermind is someone beyond the investigators' reach.[2](https://www.boxofficemojo.com/releasegroup/gr1666863621/) • [7](https://kungfumovieguide.com/paradox/) • [11](https://www.gscmovies.com.my/paradox/) The Hong Kong International Film Festival's program describes the film as a cop-triad story that blurs the line between good and evil and questions who has the authority over who lives and who dies.[1](https://cinefan.hkiff.org.hk/movie/paradox)
## Production and series context
Wilson Yip directed the film after the success of his [Ip Man](https://www.edgepedia.org/ip-man) franchise, working again with action choreographer [Sammo Hung](https://www.edgepedia.org/sammo-hung).[1](https://cinefan.hkiff.org.hk/movie/paradox) The screenplay is credited to Jill Leung and Nick Cheuk.[4](https://www.the-numbers.com/movie/Sha-Po-Lang-Tan-Lang-%282017-Hong-Kong%29) The film was produced by companies including Bona Film Group and Sil-Metropole Organisation, with production countries listed as Hong Kong and China.[8](https://www.rottentomatoes.com/m/paradox) • [12](https://www.bonafilm.cn/product/64.html)
Although released internationally under the title Paradox, the film carries the three [Chinese characters](https://www.edgepedia.org/chinese-characters) for *sha po lang* on its title screen, marking its place in the SPL series; the third film keeps only some returning actors, playing new characters in a new story.[3](https://www.heroic-cinema.com/reviews/paradox-2017/) The South China Morning Post noted that the stand-alone story broadly recycles plot elements from *SPL II*, from karma and endangered children to organ trading and violent retribution.[13](https://www.scmp.com/culture/film-tv/article/2107980/film-review-paradox-louis-koo-channels-his-inner-liam-neeson-wilson?module=inline&pgtype=article)
## Release and box office

Reported running times differ by source: 98 minutes at its HKIFF Cine Fan screening, 100 minutes on the Malaysian and US distributor pages, and 101 minutes on The Numbers.[1](https://cinefan.hkiff.org.hk/movie/paradox) • [11](https://www.gscmovies.com.my/paradox/) • [4](https://www.the-numbers.com/movie/Sha-Po-Lang-Tan-Lang-%282017-Hong-Kong%29)
## Reception
On Rotten Tomatoes the film holds a 50% Tomatometer from 6 reviews and a 40% audience score; the IMDb weighted rating is 6.5/10.[8](https://www.rottentomatoes.com/m/paradox) • [9](https://www.imdb.com/title/tt7245176/ratings/) Critics singled out the action and the central performance. Edmund Lee of the [South China Morning Post](https://www.edgepedia.org/south-china-morning-post) gave it 3.5 out of 5, writing that few genre fans should feel short-changed by Yip's brutal action showcase.[8](https://www.rottentomatoes.com/m/paradox) James Mudge of easternKicks called it one of the more brutal Hong Kong thrillers of recent years, boosted by the cast and Sammo Hung's work, while Ed Travis of Cinapse judged the action weaker than in the first two SPL films.[8](https://www.rottentomatoes.com/m/paradox) Kung Fu Movie Guide praised Louis Koo's strong central performance, for which he won the Hong Kong Film Award for Best Actor, while finding the fight scenes irritatingly edited and laden with wire work.[7](https://kungfumovieguide.com/paradox/) • [14](https://www.filmarchive.gov.hk/documents/6.-Research-and-Publication/06-02-Filmmakers-Search/English/Louis-KOO_e.pdf) A Heroic Cinema review highlighted Koo's meatworks fight, an escalating series of encounters set to electro-rock music, and a wordless dramatic scene at an intersection as the film's standouts, while noting that the larger context of systemic corruption is referenced but never clearly demonstrated.[3](https://www.heroic-cinema.com/reviews/paradox-2017/)
