While en route to a hotel in a taxi, Theresa is joined by Susan, and the two are attacked by Cordell, who kills the cabbie and forces Susan and Theresa off the road. After handcuffing Susan to the steering wheel of a car and sending her into the busy streets, Cordell kills Theresa by snapping her neck. Gaining control of the car, Susan crashes and is found and given medical attention.Elsewhere, a stripper named Cheryl is attacked in her apartment by Steven Turkell, who has strangled at least six other exotic dancers. As Turkell brutalizes Cheryl, Cordell arrives, disposes of a pair of officers earlier called by Cheryl, and helps Turkell escape. Grateful for the help, Turkell befriends Cordell and takes him back to his apartment, where Cordell stays for a short while. After Cordell leaves, Turkell goes out to find another victim but is identified at a strip club by Cheryl. He is arrested and placed in a holding cell by Susan and Detective Lieutenant Sean McKinney. ........
