That Demon Within

By a strange twist of fate, dutiful Hong Kong policeman Dan saves the life of the leader of a violent gang of armed robbers. When they commit another crime, Dan is determined to put an end to their activities. He works with the leader, whom the gang had betrayed, to engineer a plan to wreak havoc within the gang and let the gangsters kill one another. But it becomes increasingly obvious to Dan and to his colleagues that Dan is suffering from a severe mental disorder, and Dan finds that instead of upholding the law as a righteous police officer, he has now become a fugitive wanted for murder.

Directed by Dante Lam Chiu-yin, That Demon Within leans on a strong ensemble — Daniel Wu, Nick Cheung Ka-Fai, Andy On Chi-Kit — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about action titles of 2014.
