Detective Raimy Sullivan never got the chance to really know her father. When she was only eight years old, NYPD cop Frank Sullivan left his family to go undercover on a case, but got corrupted and was later killed.
It's now 20 years later, and Raimy is shocked when she hears her dad's voice come through his broken old ham radio. Somehow he is transmitting over the airwaves from 1996. Raimy is able to warn her dad that the sting he is on will lead to his death, helping him to survive the attempt on his life.
But Raimy soon finds out that changing history has had a dramatic affect on her life in the present, along with tragic consequences. Separated by 20 years, Raimy and her father have reunited on a frequency only they can hear, and they now must work together to rewrite the story of their lives.
