After Batman rescues an abducted child from Bane for a ransom, Lady Shiva approaches Batman to inform him of a Lazarus Pit intruder and requests him in identifying who it was. Batman agrees to do so while Catwoman steals the ransom with Batman following her. During the pursuit, Batman's grapple is shot by a masked vigilante in the distance, leading to his fall and skull cracked. He is recovered by Batgirl, who takes him back to the Batcave where Bruce’s butler Alfred Pennyworth contacts his childhood friend now renowned brain surgeon - Tommy Elliot to treat his skull. Alfred then gives him a new bulletproof batsuit. Meanwhile, Catwoman delivers the ransom to Poison Ivy, who has been controlling her with a hypnotic kiss. The same masked vigilante that shot Batman confronts Ivy about the ransom and gives her Kryptonite.

At Blackgate Penitentiary, Amanda Waller retrieves Bane after his attempt at escaping his prison transfer. Later, Batman reluctantly teams up with Catwoman to track down Ivy to Metropolis. While there, Batman confronts Lex Luthor, now a probationary member of the Justice League after helping them defeat Cyborg Superman, about information on a delivery list of an ethylene compound utilized by Ivy. Ivy uses Kryptonite poison to take control of Superman and orders him to kill Catwoman and Batman. Catwoman threatens to push Lois Lane down a building to calm Superman down. Selina interrogates Ivy, who reveals she was hired by a mysterious vigilante calling himself "Hush".

Hush frames Joker for Tommy’s death, angering Batman. Following Tommy's funeral, Bruce deduces that Hush knows he is Batman. While on patrol, Hush grabs Batman’s attention and confronts him, although Hush tricks him by using mirrors. He then threatens to hurt everyone close to him prompting Batman to reveal his identity to Catwoman. Bruce takes Selina to the Batcave where the latter meets Dick Grayson / Nightwing, Alfred, and learns of Bruce's son Damian. Unbeknownst to Batman, Hush lures Dick and Selina to Tommy’s grave where they are attacked by Scarecrow. Scarecrow infects Dick with his fear toxin leading him to be sent back to the Batcave to recover allowing Hush to kidnap Selina, taking her to an abandoned factory.

Commissioner Jim Gordon informs Bruce of a break in at Tommy’s office. Batman investigates the break in and learns one of Tommy's patients was someone using the alias of crossword puzzle inventor Arthur Wynne was suggesting that Riddler was behind the break in. While interrogating Riddler at Arkham Asylum, Batman realises that he is actually Clayface disguised as him and learns that Riddler was Hush all along through a voice communicator. He then detects that Arthur Wynne was just an anagram of the factory where Selina is being held captive by Riddler. There, Batman taunts Riddler as the effects from the Lazarus Pit are wearing off and frees Selina, who kills Riddler in the process. Selina then decides to call off her relationship with Bruce due to his moral codes.
