Japanese horror. When a young computer hacker is found dead, his friends explore his flat and discover strange marks on the wall and a mysterious floppy disk. Analysing the disk for clues, they inadvertently release a virus that broadcasts web feeds to several different PCs, even if those computers are not actually on. What the web feeds reveal is a strange, ghostly environment populated by shadowy figures - ghosts who inhabit the digital world, and who are slowly forcing their way through into our dimension, with devastating results.
