Two muggers are found dead in a back alley of Philadelphia after robbing a woman, Lauren Kyte, at an automated teller machine. Mulder and Scully investigate the case when called in by a pair of agents from an unknown agency. The bodies are found to have an electrical charge and their throats have been crushed from the inside. Meanwhile, Lauren sees her boss, Robert Dorlund, and resigns due to her grief over the death of Dorlund's partner, Howard Graves, who supposedly committed suicide weeks before.
