Second part of the Nightmare Collection with Dead of the Brain and Dead of the Brain 2. In the first half of the 21st century, humanity started building space satellites, trying to sustain the working conditions in outer space by using a drug known as Marine Philt. Eventually the project was abandoned. One of the deserted satellites fell onto the Earth, causing a radioactive accident that forced the inhabitants of Neo Tokyo to dwell underground. One day, a young man named Seed heard a news report about a gruesome murder that occurred in a research facility. Together with his friends, Seed ventures into the building, only to discover another horrifying result of the satellite crash, which may put the entire city in immense danger.
