I Come with the Rain is a 2009 neo-noir thriller written and directed by Vietnamese-born French director Tran Anh Hung, starring American actor Josh Hartnett.
The search leads Kline to cross paths with local organized crime syndicate boss Su Dongpo, who is making trouble for the underworld, triggered by an overriding passion for his drug-addicted girlfriend Lili.
Caught in the crossfire between the Hong Kong police and Su Dongpo's mafia drug ring which is also hunting for Shitao, Kline finds himself alone, in this unknown city, when Meng Zi is victim of an assassination attempt and is hospitalised.
Leaving behind his 5-star hotel for a shabby murder scene apartment in order to get inside the mind of Shitao, Kline gradually loses himself in the terrifying memories of Hasford, whose speciality was dissecting his victims' limbs while they were still alive, then reassembling them into installation sculptures.
After a few weeks immersed in his haunted memories, torn between good and evil, Kline is about to leave Hong Kong when he finds Shitao, who has become a mysterious vagrant with healing powers.
