Fuse [Film and TV Commentary]

Crime Squad member Sha Zhan Ma Jun (played by Donnie Yen) is committed to catching criminals. His extraordinary skills often take excessive shots because of his eagerness to catch thieves. The police have been collecting criminal evidence of Vietnamese gang brothers A Zha (played by Lui Liangwei), Tony (played by Chou Zhaolong), and A Hu (played by Xing Yu), so they sent Watson (played by Louis Koo) to infiltrate among them as an undercover agent. The three brothers are ruthless and want to get rid of Ah Shan, the thorn in their side. After Zha was caught, Tony also discovered Watson's true identity and wanted to kill Watson and other witnesses to rescue his eldest brother. Watson's girlfriend Qiudi (played by Fan Bingbing) was held hostage, and Watson had to give up testifying against A-Zhao. Watson and his girlfriend were both taken hostage, and Ma Jun also took Ah Zha to rescue Watson.
