Infinite loops of Rebirths

I have a question. A man should attain enlightenment to liberate himself from cycle of rebirths and every other aspects. What if a **MAN** don't even care to try out to attain enlightenment. Will he be stuck in a cycle and no place to stop his process of rebirth until he attains enlightenment. Does he be a prisoner of this birth cycle. Is there no way for him to escape until he attains **Enlightenment**. What is the end of this birth cycle? I don't have in-depth knowledge in Buddhism or the question I ask. So please correct me if I am wrong.
