The story introduces Hush, a man who knows which buttons to push to wreak havoc on Batman's life. Hush arrives in Gotham City and immediately pulls the strings, making the worst villains in Batman's rogues gallery do his bidding. Always toeing the edge between good and evil, Catwoman finds herself caught up in Hush's scheme and drawn deeper into Batman's life than she ever imagined.

Old relationships are reexamined and new alliances are formed, but Batman remains in the bull's-eye, and with each chapter Hush gets closer to exacting his revenge--a long-standing debt to be repaid.
