Brenda goes toe to toe with the tricky attorney of a man suspected of a brutal rape and murder.

Fritz's sister agrees to use her psychic powers to help the Priority Homicide Division resolve one of their cases, and while her abilities appear to help her understand how Brenda works, they don't seem to stop her from offering misguided advice.

Brenda and Fritz's attention is diverted by problems on the job even though their wedding day has finally arrived, and bad blood between the members of the Priority Homicide Division threatens to cause one of the officers to leave the department.
