A prisoner is caught in a Matrix 

Imagine what people living in the year 1967 would think the future would be like.

This is a sci-fi adventure, seen thought the eyes of someone living in 1967, who sees his future of 1998. (Of course he got it wrong.)  In this future world of 1998, prisoners are kept in sleep states and punished by their own thoughts that are fed into their brains through a chip. If you don't get the story, you will still enjoy the bondage in it.
