A genius doctor has stayed inside a sealed room in a lab for 15 years following her arrest for the murder of her parents. Now architecture professor Souhei Saikawa, and his student, Moe Nishinosono go to her isolated island to visit her.

The camping trip to Himeka island gets off to a great start with a BBQ and lots of alcohol. But when Moe visits Dr. Magata's lab, things take a sinister turn.

Nobody can believe their eyes at the corpse that appeared from within Shiki's room. They try to figure out what happened, but the room was completely closed off, which only makes the plot thicken.
