Plot
Principal Investigator William Luk (Louis Koo) and Chief Investigator Ching Tak Ming (Kevin Cheng) are investigating a smuggling and corruption case when they uncover a customs corruption case connected to an international human trafficking ring.6 The syndicate is headed by King (Rosyam Nor), with Siu Cheuk-Ah (Michael Tse) as the mastermind; Ching's younger brother Ching Fai Hung (Bosco Wong), who works in customs, is also involved.6
Judge Emma Pong (Jessica Hsuan), described in the film as the chief justice of Asia, is secretly protected in Hong Kong by G4 officer Lau Po Keung (Julian Cheung) while the case unfolds, and Ching Tak Ming must choose between family loyalty and justice.6 The Australian Classification Board describes the film as an action crime drama in which ICAC officers investigate a crime syndicate involved in the trafficking of young women, with themes of criminality including human trafficking and official corruption.2
The Storm series
The Storm series follows ICAC investigator Luk through a different corruption case in each film: financial corruption in Z Storm (2014), illegal gambling in S Storm (2016), money laundering in L Storm (2018), prison corruption in P Storm (2019), and human trafficking in G Storm.4 All five were directed by David Lam and starred Louis Koo, with the scale of the cases expanding from police and finance matters toward prison, customs, and international crime.4
The title's letter has a specific meaning in this entry: G refers to two units, the police VIP protection unit commonly known as G4, and the ICAC's informant division (G division), which includes undercover agents.1
Production and release
The Hong Kong Film Industry Data compilation for 2021 lists the film's production company as Mandarin Motion Pictures, with Raymond Wong as producer, cinematography by Joe Chan, editing by Poon Hung-yiu, action design by Chung-Chi Li, and original music by Anthony Chue.3 The film was rated IIB in Hong Kong and carried the release tagline "终极反贪" (final anti-corruption).3
In Australia the film was classified MA 15+ on 6 December 2021 for strong violence, with the board noting knife fights, shootouts, and hand-to-hand combat accompanied by blood effects.2 In Taiwan, the film earned NT$330,000 in Taipei as of 28 January 2022.7 A 2023 annual report by the film's distributor listed G Storm (released as 反贪风暴5：最终章 in some markets) among its notable titles alongside Warriors of Future and Someday or One Day.8
Reception
Critical response was mixed to negative. Edmund Lee of the South China Morning Post gave the film 2 out of 5 stars, writing that Louis Koo reprised his role as a senior anti-corruption investigator in a slackly scripted film padded with action sequences, and that the fifth and final installment ended up as laughably ridiculous as the previous four.9 The Kai-Fong review graded it C, noting that the film was finished in 2020 and had to rework scenes previously planned for a Southeast Asian location, and criticized the narrative's logic while observing that the series bid farewell to the character of William Luk.10 The Cinespot review scored it 7 out of 10, judging that the finale restored the entertainment value some viewers found missing in P Storm through its gunfights and action staging, though its screenplay was criticized as overly episodic and too short at around 90 minutes to develop the cast's emotional arcs.11
