Past and present collide when an Alzheimer's patient's fragile memory holds the key to solving mysteries dating back to World War II-including a long lost secret love affair. Music professor Gus LeGarde is just doing a favor for a friend when he agrees to play piano for church services at a local nursing home. He doesn't expect to be drawn into a new friendship with an elderly Alzheimer's patient dubbed "the music man" or to stumble across a decades-old mystery locked inside the man's mind. Octogenarian Kip Sterling doesn't know his own name-but he speaks Gus's language, spouting jazz terms like "cadence" and "interlude" and "riff." He's also obsessed with "his Bella," but nobody knows who she is. When Kip is given a new drug called Memorphyl, he starts to remember bits and pieces of his life. Gus learns Bella was Kip's first and only love, but their relationship was shrouded in scandal. Intrigued, Gus agrees to help search for her. Could she still be alive? Horrified when the miracle drug suddenly stops working and patients begin to backslide, Gus panics. Can he help Kip find his beloved Bella before his newfound memories disappear?
