It's a full moon in New Orleans, and sure enough, all night long, the calls for the EMT's seem to get crazier and crazier: the victim of a machete hacking, the man whose finger is bitten off by a dog, the guy stabbed by a man dating his ex-wife. Meanwhile, two cops keep their perfect record of chasing down suspects in foot races intact, and a fire chief confronts his fear of rats.

Police officers pursue suspected drug dealers, while Keeley saves a group of partiers from a violent schizophrenic.
