People who can't sing get haunted by a ghost called Premika that lives in a karaoke booth.

A haunting spirit of an unknown girl who dwells in a karaoke booth, named "Premika" after the clothing tag she wears. One night, someone accidentally switched on a karaoke booth that Premika possesses in. Then, she was awakened from the death, and is ready to torment whoever that sings incorrectly or out of tune, bringing together a horrifying, laughing, amusing and tuneful haunt.—M Pictures
