It looks like you're searching for the Vietnamese film (possibly misspelled as "Ma Muoi"), or you might be referring to a horror film titled "Ma Muối" — but there is no widely known Vietnamese film with that exact name.
However, to give you the most helpful answer for your request:
If you meant — that’s a lesser-known Vietnamese movie. If you were looking for a horror movie, you might be thinking of "Muối" (Salt) or another Vietnamese horror film.
