Psychologist Pari Logan does not believe in ghosts. When Ghost Whisperer Sam Preston shows up claiming her office is haunted by the famous ghost of Downtown Strawbridge, she wants nothing to do with him or his ghost-hunting nonsense. But all of Downtown Strawbridge is caught up in ghost hysteria. Worse, her friend Melissa Stathem has a ghost story of her own and isn't happy to be teased about it. Before she can say, "Boo!" Pari finds herself drawn into Melissa's challenge to the Downtown Divas: Attend all the Ghost Whisperer's events and if they still don't believe in ghosts by Halloween, she'll stop pestering them. Being thrown constantly into the path of the Ghost Whisperer who, for some reason, she keeps kissing, is the last thing Pari needs. No, what she needs is a man who is her type: professional, serious, and rational. A man like gorgeous Eric Lawson. Who will win Pari's logical heart? The perfect guy? Or the one she caught on his hands and knees peering under office door looking for a ghost?
