Alerta Total (1997)

Year after year, just after the monsoon season has finished, thousands of families travel to a bleak desert in Gujerat, India, where they will stay for an endless eight months and extract salt from the earth, using the same painstaking, manual techniques as generations before them. Director Farida Pacha spent a season with one of these families, observing the very particular rhythms of their lives.

When Hong Kong is rocked by multiple gruesome murders, the police forms a task force to investigate. Jun, once a brilliant detective who suffered a mental breakdown, begins his own investigation. Eventually, the police learn that the murder victims are all suspects of cold cases being rubbed out by a figure known as "The Sleuth". Now, Jun and a detective from the task force are on a race against time to beat the brutal killer at its own game.
