After a rival circus promoter is also murdered, Jess is knocked out with a chloroformed rag and dumped in a burning motel room, only to be saved at the last minute by a recently released Neil.
Later, she confronts the true murderer under the big top and somehow gets him to reveal his actions by convincing him to theorize about what he WOULD have done if he HAD committed the murders. When Jessica realizes this won't be enough for a court of law to convict the man, she has a couple of carnies start shoving him into a cage with a hungry tiger until he panics and reveals where he hid a bloody hacksaw, which is enough to seal his fate.
The episode ends with Jess revealing to Courteney Cox and her father that Neil is alive and well. The father considers faking his own death to escape from his terrible wife.
