Plot
Tom Selznick was an up-and-coming concert pianist until he developed stage fright while attempting to play a complex piece, "La Cinquette". Five years later, he is slated to appear in Chicago for a comeback performance, dedicated to the memory of his late mentor, pianist and composer Patrick Godureaux (who composed "La Cinquette"). Godureaux posthumously acquired massive media coverage due to the mysterious disappearance of his vast fortune. Tom's return to the stage is prompted by the encouragement of his actress-singer wife, Emma.
As Tom arrives at the theater, his friend Norman (conductor for the evening) offers Tom assurance that he will perform well. Shortly thereafter, a house usher hands Tom a folder of sheet music. Within, he finds the manuscript to "La Cinquette" and discards it. During the concert, Tom finds a note written on his sheet music that reads "Play one wrong note and you DIE". Believing it to be a prank, he ignores it, only to find further notes that threaten Emma, as well as a laser dot that tracks his movement.
Disturbed, Tom leaves the stage, shocking the audience. He returns to his dressing room, where he receives a text that instructs him to locate and wear an earpiece, allowing communication with the would-be assassin, Clem. When Tom returns to the stage, Clem demonstrates the stealth and range of his silenced rifle by firing a shot into the floor to Tom's left; no one else notices.
