Watch Accumulator 1

"Accumulator 1" is a Czech horror movie. In it, television sets are living beings that feed vampirically on humans. If a person is filmed, that act of filming creates a vampiric double who feeds on the original every time they turn their television on. Consequently, people die in front of their sets. A few people, however, do know how to resist, and they try to teach others how to fight back as well.
