Banba watches police interrogating a young man who claims he was taken to an abandoned industrial greenhouse by some bullies. They are disturbed by the wild plant growth in the building, and find what appears to be a person embedded in a vegetal sac. The humanoid figure falls out of the sac and animated vines begin to attack the group. Those with flashlights find that light repels the vines, but batteries run out and all except the single witness succumb to the vines. At the site the next day, the police find only desiccated corpses. After the interview, Banba concludes that the young man is responsible for the deaths. Kimura appears with a team that captures the witness, now clearly non-human.
