Ghost of New Orleans

A serial killer who leaves weird masks on his victims is at large in New Orleans. His fourth victim is cellist Corey Little (Lake Bell), who goes missing on a beautiful Louisiana night. Detective Ben Chaney (Josh Lucas), who's a little too fond of the bottle, is assigned to keep an eye suspect Drag Hammerman (Terrence Howard). While standing in front of Corey's house, a kid tells him the house is haunted.

When Chaney goes inside, sure enough, he spots Corey's ghost, who asks him to help find her killer. Unfortunately, when he shares this information with others, they think he's not only crazy, but a drunk.
