The Gravedancers (2006)

The former friends Harris, Kira and Sid reunite for drinking after the funeral service of an old friend that died in a car accident. When the bar closes, Sid proposes to go to the Cresent View Cemetery to say farewell to his friend and drink more. Once there, Sid finds a letter in a tombstone, reads it and they dance on three graves. On the next days, weird things happen in the house of Harris and his wife Allison, but Allison believes it is Kira, who has a crush on Harris, stalking them. They go to Kira's house and find her wounded in a completely destroyed place. Later Sid calls them and they are introduced to the paranormal investigators Vincent Cochet and Frances, who tell them that Sid read an ancient spell that cursed the trio and brought back the ghosts of the graves from the damned sector of the cemetery where they danced. He also discloses that Harris and Allison are being haunted by an insane ax murderer pianist; Kira by a sadistic rapist; and Sid by a pyromaniac. They have to break the curse or survive for an entire cycle of the full moon when the curse would finish, while the ghosts are getting stronger and stronger. [imdb]
