Crescendo

Drawn to the spectacular south of France to research the late composer Henry Ryman, music student Susan Roberts (Stefanie Powers) encounters his son, drug-addicted Georges (James Olson) and his eccentric family. Investigating the haunting strains of an unfinished Ryman concerto leads Susan to discover an empty piano… and a brutally savaged mannequin! Georges tells her she's the lookalike of his lost love. But Susan may not be the only one at the villa with an eerie doppelgänger.
