"Having someone get murdered at your wedding has to be the worst." Scott Deering, cellist for the Los Angeles Philharmonic, doesn't usually play weddings. But a friend's family emergency finds him reluctantly anchoring a college string quartet at the wedding of a couple with more money than taste. When his second violinist goes missing after the ceremony, Scott is determined that the show must go on - until the violinist turns up dead and Scott's day goes to hell. Jamie Brodie and Pete Ferguson are attending the lavishly over-the-top wedding of an acquaintance of Pete's when Jamie spots a ghost from his past in the string quartet - Scott Deering, the last guy he dated before Pete. The murder at the wedding is shocking, but it's not Jamie's business - until a theft from the music library at UCLA sucks him into the investigation. All Jamie wants to do is finalize the plans for his own wedding to Pete, but first he has to join forces with Scott to track down a killer - and deal with another ghost that throws everyone's lives into turmoil.
