Generally speaking, "film noir" are stylistic crime dramas with cynical attitudes and sexual overtones...mostly from the '40s and '50s. Most are high-end B-flicks that portray a hardboiled private detective hired (to track down a murderer, kidnapper, etc) by some good looking, socialite dame/broad who has attitude to match. Throw in a few tommy guns, a double or triple-cross, some 1920s era gangsters, a dirty cop or two....and there you go.
