Monk is horrified when he learns there's going to be a blue flu in San Francisco - until Capt. Stottlemeyer explains that it just means the police plan to call in |sick| until they get a better contract. The good news is the labour dispute will give Monk a chance to get back on the force. The bad news is it means he'll be a |scab|. But before he knows it, Monk has his badge back and his own squad to command. Unfortunately, some of the squad members make Monk look like a paragon of mental health. But despite that, they'll have to pull together to catch an astrologer's killer.
