Doug Harris is a loveable but socially awkward groom-to-be. He doesn’t have a best man, with less than two weeks until he marries the girl of his dreams. Jimmy Callahan (Kevin Hart), is the owner and CEO of Best Man Inc., a company that provides flattering best men for socially challenged guys in need. What ensues is a hilarious wedding charade as they try to pull off the big con. In the meantime an unexpected budding bromance emerges between Doug and his fake best man Jimmy.
