Please answer the following question: Build a movie plot around this: What goes on a rampage through Tokyo? The Z-001
A:
Roujin Z is set in early 21st century Japan. A group of scientists and hospital administrators, under the direction of the Ministry of Public Welfare, have developed the Z-001: a computerized hospital bed with robotic features.[2][3] The Z-001 takes complete care of the patient: it can dispense food and medicine, remove excretory waste, bathe and exercise the patient lying within its frame. The bed is driven by its own built-in nuclear power reactorand in the event of an atomic meltdown, the bed (including the patient lying within) would become automatically sealed in concrete.[4] The first patient to be "volunteered" to test the bed is a dying widower named Kiyuro Takazawa. He is an invalid who is cared for by a young nursing student named Haruko.[5] The electronic elements within the Z-001 somehow manage to transcribe Takazawa's thoughts through Haruko's office computer, and he uses the communication to cry for help.[4] Although she objects to such treatment of elderly patients, Haruko begrudgingly seeks the aid of a group of computer hackers in the hospital's geriatric ward to create and install a vocal simulation of Takazawa's deceased wife in the Z-001.[2][3] However, once Takazawa wishes to go to the beach, the Z-001 detaches itself from its moorings and escapes from the hospital with the man in its grasp.[2][6] Haruko's fears are then justified, as it is discovered that the bed is actually a government-designed, experimental weapons robot.[3][5]
