When his rich wife dies, Cheev (Thanavate Siriwattanagul) stands to take everything. Looking forward to starting his new life with mistress Rossukhon (Arachaporn Pokinpakorn), Cheev moves her into the luxury villa they’re about to inherit. There’s one small catch though – the property will only become Cheev’s once his wife’s body has spent 100 days with them both in the house, lying in state in an ornate glass coffin.

Blindsided by the truth about their living arrangement, Rossukhon is understandably freaked to be sharing the house with Cheev’s dead wife. As for the dearly departed Lunthom (Arachaporn Pokinpakorn), she’s not exactly resting in peace, and Rossukhon is soon tormented by ghostly visions of her spooky predecessor. Can Cheev convince Rossukhon to hold her nerve long enough to inherit the house? And what does either woman see in a deadbeat like Cheev anyway?

This Thai ghost story by director ​Vathanyu Ingkawiwat goes heavy on the melodrama, leaning into the tropes of the Pi Tai Hong subgenre. There are few true surprises in store, although the imagery is suitably ghastly (if you’re creeped out by the dark haired female ghost archetype, that is) especially as Lunthom’s ghost becomes more emboldened by Cheev and and his mistress rutting all over her home.

Far more appalling than anything Lunthorm does is the behaviour of Cheev, who acts exactly how you might expect a man named ‘Cheev’ to act. As flashbacks detail the collapse of his marriage and beginning of his affair with Rossukhon, the real monster of the piece is revealed. The mistress is no angel either, but one soon realises that Lunthorm would be better off haunting her wasteman husband instead.

Tomb Watcher is far from revolutionary cinema, but it possesses a certain soapy charm.
