Mute Witness (1995) DVDRip

In Moscow, the clumsy Director Andy Clarke is making a slasher movie in a studio set with a Russian and American cast and crew. The woman responsible for the make-up is the mute Billy Hughes, who is the sister of Andy's girlfriend Karen Hughes. One day, Billy needs to find a mask for the shot on the next day and she stays after hours in the studio set seeking out the object. However, the janitor locks her in the studio alone, and Billy cannot find a way out. When Billy sees light in the studio, she accidentally witnesses the Russians Arkadi and Lyosha making a porn snuff movie and brutally killing a woman. Billy succeeds to escape, but the police officers do not trust her. Also, the powerful Russian mafia chases her, believing that Billy has a diskette with evidence against the mobsters.
