Alright, I just watched the pilot episode last Thursday. In the episode:
The main detective was investigating a murder in 2008, and is hit by a car while chasing a murderer down the street, and is transported back to 1973 where the rules are a little different. While in 1973, he investigates a murder that parallels the one he is investingating in 2008. During that time, he hears the voices of doctors examining him through radios, Television, and music.
Here is how it ends:
When the murderer is caught, the boy who looked up to him will grow up to be the man who is in the murder in 2008.
