Thirty-six year old homicide detective John Sullivan lives in the same Queens, New York house in which he grew up with his firefighter father Frank Sullivan and nurse mother Julia Sullivan. Frank died on October 12, 1969 (when John was only six) on duty in a warehouse fire. Despite Frank dying when John was so young, John remembers his father well as he has a keepsake book of photos and news clippings about Frank, who was a huge Mets fan. Almost thirty years to the day of Frank's death, John finds Frank's old ham radio, which Frank used to use all the time to speak to people around the world. A discussion about the 1969 World Series with the first person he makes contact with on the radio makes John ultimately come to the realization that he is speaking to his father who is using the exact same ham radio and sitting at the exact same desk in the exact same house exactly thirty years earlier. Although they don't know the reason for being able to contact each other, John tries to use whatever knowledge he has to help his father, especially in averting the cause of his death. But John and Frank learn that knowledge is a powerful tool which can result in both good and bad as John works on a "new" thirty year old on-going case of murdered nurses, the case coined the "Nightingale murders" which has a personal connection to the Sullivan family.
