Alex is appalled at her colleagues' attitude when a prostitute complains of being attacked at knife point. To them, she's just another prostitute and they're not willing to go out of their way to do anything about it. She manages to have an impact on DCI Gene Hunt, however, when she finds a connection to a murder and manages to convince him that there is someone very sick behind these attacks. They focus their interest on someone who is a member of the same choir as the dead woman and another who was attacked. Hunt doesn't believe for one minute that the prostitute who complained of the rape was the victim but does take Alex seriously enough to go after the man. In the process of the investigation, Alex meets someone from her future.
