The world of dreams can be an incredible window into the psyche, showing one's deepest desires, aspirations, and repressed memories. One hopeful tech lab has been developing the "DC Mini," a device with the power to delve into the dreams of others. Atsuko Chiba and Kosaku Tokita have been tirelessly working to develop this technology with the hopes of using it to deeply explore patients' minds and help cure them of their psychological disorders. However, having access to the deepest corners of a person's mind comes with a tremendous responsibility. In the wrong hands, the DC Mini could be used as a form of psychological terrorism and cause mental breakdowns in the minds of targets. When this technology is stolen and people around them start acting strangely, Atsuko and Kosaku know they have a serious problem on their hands. Enlisting the help of Officer Konakawa, who has been receiving this experimental therapy, they search both the real and dream worlds for their mental terrorist. A beautiful therapist named Chiba Atsuko and a genius scientist Tokita Kosaku work for a psycho-medical institute. Tokita invented the DC-mini. It is an epoch-making device that brings them into a patient's dream and enables them to monitor the patient's inner world in order to cure him or her.However, one day, the device was stolen by someone. Since then the dreams of those concerned with the project have been attacked one by one, and something is starting to go terribly wrong. Chiba begins to investigate the matter, using another identity though. She becomes the Dream Detective Paprika who synchronizes with other peoples' dreams to remove their trauma. She rises against the dream terrorist who uses the DC-mini that is strong enough to destroy ones personality. But who is this criminal, and why commit these crimes? When the manipulated dream connects with the reality, an inner world no one has ever seen is revealed...
