Film Synopsis

Plot Summary

Myles Clarkson, long ago frustrated in his hope for a career as a pianist, is now a musical journalist and interviews Duncan Ely, perhaps the world's greatest virtuoso on the instrument. At first annoyed with Myles's presence, Duncan soon takes notice that Myles's hands seem perfect for the piano. From that point, Duncan and his adult daughter, Roxanne, strongly pursue a friendship with Myles and his wife Paula. Paula does not much like Duncan and especially dislikes Roxanne. While Paula is disturbed by the level of attention being paid to them by Duncan and his daughter, Myles is honored to be considered a friend by Duncan, who is dying of leukemia. Unbeknown to Myles and Paula, Duncan and Roxanne are Satanists. As Duncan's physical body nears its end, father and daughter perform an occult ritual which transfers Duncan's consciousness into Myles's body.
