1990s small town China. A woman’s body washes up in the local river. The chief of police, Ma Zhe, is tasked with heading up the investigation. An obvious perp leads to a hasty arrest, though the mystery lingers in Ma Zhe’s mind. What kind of darkness is truly at play here? Director Wei Shujun’s murky throwback film noir, gritty, textured film grain captures the pulpy proceedings. Torrents of rain envelop the characters as they descend into madness in pursuit of the truth. Equal parts atmospheric tour-de-force and beguiling puzzler, Only the River Flows is a masterfully styled ode to a bygone cinematic era and a sharp-edged portrait of provincial paranoia. The film, starring Zhu Yilong, is based on Yu Hua’s popular short novel Mistakes by the River.
