Jing Wong helped launch the careers of many famous Hong Kong directors, others never really found their way from underneath his wings. Siu-Hung Chung is such a long-time collaborator (though to be fair, Chung was already quite busy before teaming up with Wong). Set Up is a pretty decent film, with both directors clearly making an effort.
Moon is a writer of horror novels. The day before her wedding she goes in for eye surgery, that night she stays with her sister. The house where they sleep over isn't empty though. There are three criminals who are also hiding inside the house. With Moon's eyes still recovering, staying out of their grasp won't be easy.
The performances aren't too great, and the plot is pretty basic, but Wong and Chung do their best to give the film a little extra visual flair to compensate. And that works pretty well. The short runtime and decent pacing definitely help too. Not the greatest thriller, but pretty good filler nonetheless.
