Premise
In 2016, NYPD Detective Raimy Sullivan discovers that she is able to speak to her deceased father Frank Sullivan in 1996 via his old ham radio. Her attempts to save his life trigger the "butterfly effect", changing the present in unforeseen ways. To fix the damage, she must work with her father across time to solve a decades-old murder case.

Main
An NYPD detective who experiences an unusual weather phenomenon that allows her to communicate with her late father through radio transmissions. Born and raised in Queens, Raimy is stationed at the 21st Precinct (the same precinct her father worked out of in 1996) and has been since the start of her career in 2008. She achieved the rank of detective in 2014. After changing the timeline by conversing with her father, Raimy seems to be the only one who notices the changes. Now, she and Frank work across time to solve the Nightingale murders before her mother can become the killer's next victim.
