Television reporter Riley Spartz is recovering from a heart-breaking, headline-making catastrophe when a long-time police source drops two homicide files in her lap in the back of a dark movie theatre. Both cold cases involve women named Susan strangled on the same day, one year apart. Last seen alive in one of the poorest neighbourhoods, their bodies are each dumped in one of the city's wealthiest areas. Riley senses a pattern between those murders and others pulled from a computer database of old death records. She must broadcast a warning soon, especially to viewers named Susan, because the deadly anniversary is very fast approaching.

But not just lives are at stake - so are careers!
