Leo Woodall stars as a gifted young piano tuner whose heightened sense of hearing draws the attention of criminals, who see his talents as useful for opening safes as for tuning Steinways. With his once-promising musical career over, he works across New York with his mentor Harry Horowitz (Dustin Hoffman), encountering a range of characters, including composition student Ruthie (Havana Rose Liu), with whom he forges an unexpected connection.
