Molecular man terrifies the world!
The Tokyo police are investigating a growing number of disappearances. They realize there are strange occurrences where they find only people’s clothing, but the people have vanished. A nearby fisherman tells them he and others from his village found an abandoned merchant ship and on board they too found clothing but no people. They also found a gelatinous green glowing substance that attacked them and consumed some of them. The police soon realize that they are dealing with a monster created as a result of H bomb testing. They also realize the creature is living in the sewer system.
