An android built to be a son becomes something neither of his creators expected. The robot's broken mind isn't a problem to solve, it's the entire point. Two rival scientists circling each other through their creation, neither willing to admit the other was right. This is a 1977 show that treats its machine like a person before most science fiction knew how to ask the question.
On a remote artificial island in 2015, Dr. Yamanoue has built an android named Mars, hoping to raise him as a son. But Mars's neural circuits are flawed, and Yamanoue needs help from his old rival, Dr. Kawashimo, to fix them. The two scientists couldn't be more different: Yamanoue sees Mars as a weapon for national power, while Kawashimo believes the robot deserves genuine care and protection. When Kawashimo arrives with his daughter Miri, the real work begins, and Mars starts to develop beyond anyone's expectations. As military forces circle the island hungry for control of such advanced technology, Mars must figure out who he really is and where his loyalties lie. The android becomes caught between competing visions of his purpose, forced to choose between the destructive ambitions of those who created him and the humanity that Kawashimo insists he possesses. What emerges is a tense science fiction story about artificial consciousness, the responsibility of creation, and whether a machine can ever truly be free.
