During her American debut, concert pianist Magdalena Estrada is center stage when a man falls from the catwalk above, smashing the piano and setting off a chain of events that uncovers a sinister case of impersonation, kidnapping, and family secrets. In a gripping blend of mystery and drama, a deputy chief and his detectives unravel a tangled web involving identical twins, a long-buried past, and a terrorist plot—culminating in a triumphant encore no one saw coming.
