They identify a suspect and use Lucy to lure him into a trap, but their plan goes badly awry and Lucy is assaulted. Shaken, the women take a different approach, contacting former war department members. Susan plans to meet with a psychiatrist whom she believes has helpful information, completely unaware of the danger that awaits her.
