This movie is similiar in cast and sets to "Vampire Settle on Police Camp". Sandra Ng and the gang are assigned to a camp to train for a secret mission. After fooling around w/ an Ouiji board they unleash a ghost hellbent on killing them all. While most of it is lame comedy sketches it finally builds up to a pretty good climax. Yuen King is the ghost and a good choice for the part. Had she had more screen time the movie would've fared better. Still, I really enjoyed her in the final reel. She's been so good in the Stephen Chow films but this early role for her is a nice change of character. Worth a look if you like her.
