A Sudanese man from Louisville who fled genocide in Darfur is found shot dead while at work at a clothing store. The store's video surveillance system didn't identify the suspects, so Det. Rick Arnold must hit the streets to find any leads in the case. Next in Birmingham, a young man is found murdered in his home. His girlfriend was also shot multiple times and is clinging to life. But she is able to name two potential shooters. Investigators must determine whether these two suspects are indeed the killers.
