Synopsis

A scientist invents a machine to record sound waves onto solid objects such as rocks and tests the playback on a rock taken from an old temple where the black arts were practiced. At first he hears his voice from the test he made, but then sounds continue as the machine plays back a chant that was stored ages ago on the rock and a demon appears.
