Paper rejection based on unfair review
I feel the only way out is to resubmit it for another conference in near future.


That about sums it up. Negative reviews and rejections are hard to swallow. They are common in academia and you cannot let them get to you. The best thing to do is step away from the manuscript. If you need to cry, cry. If you need to scream, scream. After a while, generally for me a week or so, try and look at the reviews again. If they still piss you off, step away from them again. Once you can read the reviews objectively, start to tackle them. This might mean agreeing with the reviewer, or seeing where the reviewer got lost, or that the reviewer is simply a fool. Once you have taken everything from the reviews that will improve the manuscript, file it away and if necessary cry and scream again. Then resubmit the manuscript to the next conference.
