Gambling is illegal in Chicago, so bookies have been 'sitting' in people's homes and using their personal phones to take bets. Most people don't understand that this is illegal and that they won't be able to stop. When gamblers start getting beaten up and a woman is killed for trying to evict her sitter, Frank goes to work.
