After a temperamental meltdown on stage, Sean Hightower, a regretful and resentful "one-hit wonder" rock musician hoping for a comeback, returns to his girlfriend's condo seeking comfort from the woman he loves. But after letting himself in, he discovers her naked body on the bed, murdered from a bullet to the head. When the police detective arrives and sees the two taped pieces of paper on the wall with the word, "hello," on one and "goodbye," on the other, he realizes that the renowned serial killer, The Beatles Song Murderer, has struck again. In the days that follow, he reaches another conclusion—the Beatles Song Murderer is probably somebody Sean knows. But could that be possible? And if true, who could that be?
