Detective Jacob Lev wakes one morning, dazed and confused: He seems to have picked up a beautiful woman in a bar the night before, but he can't remember anything about the encounter, and before he knows it, she has gone. But this mystery pales in comparison to the one he's about to be called on to solve. Newly reassigned to a Special Projects squad he didn't even know existed, he's sent to a murder scene far up in the hills of Hollywood Division. There is no body, only an unidentified head lying on the floor of a house.
