Death Powder (1986)

In the very near future, a group of three researchers has captured a very special android named Guernica (Mari Natsuki), and have brought her to a deserted warehouse, and have tied her to cot, with a protective covering over her mouth. One researcher (Izumiya) is left to guard the Guernica, but appears to be slowly going crazy. Two of the researchers, a guy (Inukai) and a girl (Murakami) apparently have just escaped (presumably from some fallout after capturing Guernica) and are on their way back to the warehouse. Murakami tries calling Izumiya and discovers that something is wrong.
