After undercover cop Dana Baker is murdered, Fontana and Green learn that the man who killed her had discovered her identity after seeing a photograph of her in the paper revealing her as a police officer, not the undercover heroin dealer she was posing as. Investigating the story leads detectives to Eric Lund, one of the workers in Congressman Prescott's office, but Lund seems to have an ironclad alibi after an e-mail he sent comes to light.
