Rawton and Lennox investigate when a nurse is violently attacked at the nurse's home where she is living. Initially, only one witness is able to place anyone near the scene of the crime, but Lennox is determined not to have to rely on the victim to pick him out. However, Lennox seems doomed to fail as he has to take a safety training course with Meadows and a group from the relief. Proctor takes over and immediately heads straight to the victim for information. Lennox continues to try and sneak away from the training exercise to continue working on the case. After the suspect continues to play games in the interview room, he then adds assaulting a police officer to his charge sheet when he attacks Ackland.
