After finding a realtor's business card in a dead man's wallet, Chris and Rita confront the woman. In exchange for immunity, she helps the two detectives set up a sting operation against the owner of an illegal casino, who lets his clients build up huge debts, and then kills them because they cannot pay. Chris goes undercover as a big-spender, ready to play, while Rita plays the part of a blackjack dealer. Meanwhile, Chris and Annie try to work out their problems.
