During the Tang Dynasty a mysterious fog envelopes the city of Chang’an… and within the mists looms a gigantic Lovecraftian monstrosity. And there are other, smaller beasts lurking inside the fog too! The Crown Prince (Qimeng) and his loyal protector, Xiao (Liqun), who are walking the city streets at the time, escape the spike-tipped tentacles that start lunging from the foggy skies by hiding out in the Chang’an Guesthouse, where others are also trapped, including a stern swordswoman, an old hunter, and a courtesan.

Some of the people within the guesthouse decide to sneak out to get weapons from a nearby blacksmith, and as they make their way along the deserted streets they can hear the grumbling, growling sounds of the mega-monster, noises that issue from all around them in the fog. But the group is assaulted by the mist monsters, the mission to the blacksmith is aborted, and the survivors are forced to continue to hunker down inside the guesthouse.

The plot includes a backstory concerning an ethnic group, referred to as Inhumans, who were blamed for an assassination attempt on the Emperor years ago, and are now seething with hate for the rulers. There are other characters who have varying views concerning the royal family too, both positive and negative, which the undercover Crown Prince finds fascinating.

Monster-wise, as well as the gargantuan central beast that looms above the streets, the movie includes lumpy-skinned, long-tailed, leopard-sized reptile creatures that can eject organic spine-projectiles.

There are also small, bat-winged critters with heads that can completely peel back, enabling them to envelope the faces of victims. The courtesan suffers such a fate, and she kills herself afterwards, rather than live with a ruined face.

Just like the Chinese monster flick MUTANT TIGER (2022), this production is a mainland Chinese period-set creature feature that offsets its nothing-special CGI with decent production values, a stoic, solid lead performance, and a simple but interesting horror-fantasy plot. There are some interesting touches here and there, such as the nicely-handled sequence showing the courtesan doing a dance performance, which prompts Xiao to recall walking through the city before the fog came, passing by characters who will end up trapped in the guesthouse with him. The film’s quite brief running time still allows some space for a few dramatic showdowns, including the moment a vengeance-seeking Inhuman gangster releases a powerful incense designed to attract the ferocious foggy fiends to them, resulting, he hopes, in the Prince getting killed. When a boatman, a guesthouse attendant, and the steely swordswoman all die as they protect the Crown Prince from the attacking creatures, this deeply moves the Prince, and he vows to live on so that he can right all the wrongs of his royal predecessors and hopefully bring peace to the nation.

A detachment of golden-armoured royal warriors eventually arrive in the nick of time, dispensing stuff that, somehow, wards off the creatures. The humongous main monster, which has a bulky, blobby body held aloft by multiple tentacle-legs, retreats through the fog, away from the city. This movie, also known as CHANG’AN FOG MONSTER, is a contained monster-horror-fantasy yarn for the most part, set almost entirely inside the guesthouse, with the gigantic, spike-tentacled, mainly unseen boss beast treated both as a real threat and also as a kind of otherworldly symbol of the anger that has been inflamed by the perceived injustices perpetrated by those in power.
