is an annual gimmick pay-per-view, generally produced every October by WWE since 2009. The concept of the show comes from WWE's established Hell in a Cell match, in which competitors fight inside a 20-foot-high roofed cell structure surrounding the ring and ringside area. The main event match of the card is contested under the Hell in a Cell stipulation. 2012 was the fourth event under the Hell in a Cell chronology.
The professional wrestling matches at Hell in a Cell featured professional wrestlers performing as characters in scripted events pre-determined by the hosting promotion, WWE. Storylines between the characters played out on WWE's primary television programs, Raw and SmackDown. The main program involved CM Punk defending his WWE Championship against Ryback, contested inside Hell in a Cell. At Night of Champions the previous month, CM Punk and John Cena fought each other to a draw when Cena left his shoulders down while pinning Punk, making it a double pin. Following this, he continuously challenged Punk to a rematch, even while recovering from an arm surgery earlier in the month; Punk refused to accept. All the while Ryback, who was undefeated since re-entering WWE in April, had attempted to confront Punk with Punk usually escaping. This culminated on an episode of Raw where WWE Chairman Vince McMahon arrived and forced Punk to choose whether he wanted to face John Cena or Ryback. However, when Punk took too long to decide, with Cena's endorsement, McMahon made the decision for it to be Ryback. It was announced that it would be a Hell in a Cell match. At Night of Champions, Layla was originally set to defend the WWE Divas Championship against Kaitlyn, but at the event, Kaitlyn was attacked by a villainess in a masked disguise. Eve Torres replaced Kaitlyn and defeated Layla to capture the Divas Championship, and after Eve's successful defenses against Kaitlyn and Layla on back-to-back editions of Raw, Aksana was revealed as Kaitlyn's attacker on the October 26 edition of SmackDown, committing the attack under Eve's orders. It was later announced that Eve would defend the Divas Championship at Hell in a Cell in a Triple Threat Match.
The lead up to the event featured a tag team tournament to decide the number one contenders for the WWE Tag Team Championship. -The final was originally scheduled for October 15 but was postponed due to Mysterio's illness.
The event opened with Randy Orton facing Alberto Del Rio. Orton won the match after Del Rio missed an Enziguiri and performed an RKO on Del Rio for the pin. Next, Team Hell No defended the WWE Tag Team Championship against Team Rhodes Scholars. Kane was disqualified after he attacked Sandow and Rhodes, meaning Team Hell No retained the title. After that, Kofi Kingston defended the Intercontinental Championship against The Miz. Kingston executed Trouble in Paradise to retain the title. In the fourth match, Antonio Cesaro defended the United States Championship against Justin Gabriel. After countering a Suicide Dive with a European Uppercut, Cesaro executed the Neutralizer on Gabriel to retain the title. Next, Rey Mysterio and Sin Cara faced the Prime Time Players. Mysterio and Cara won after Mysterio performed a 619 and a diving splash on Young. After that, Sheamus defended the World Heavyweight Championship against Big Show. Big Show dominated Sheamus throughout the match. Big Show executed a Chokeslam on Sheamus for a near-fall. Sheamus executed White Noise on Big Show for a near-fall. Big Show executed a WMD on Sheamus for a near-fall. Sheamus executed a Brogue Kick on Big Show for a near-fall. Sheamus attempted a second Brogue Kick but Big Show avoided and executed a second WMD on Sheamus to win the title. In the seventh match, Eve Torres defended the WWE Divas Championship against Layla and Kaitlyn in a Triple Threat match. In the end, Eve executed a senton bomb on both Kaitlyn and Layla, pinning Layla to retain the title.
Main event
In the main event, CM Punk defended the WWE Championship against Ryback inside Hell in a Cell. Ryback gained the early advantage but Paul Heyman distracted Ryback, allowing Punk to spray Ryback with a fire extinguisher. Punk attempted to attack him with a steel chair but Ryback countered with a big boot, causing the chair to hit Punk, and threw Punk into the cell wall. Punk attacked Ryback with a Kendo stick but Ryback was unaffected and performed a Meat Hook Clothesline on Punk. Ryback attempted Shellshocked but the referee Brad Maddox inexplicably stopped Ryback and attacked him with a low-blow. Punk pinned Ryback with a roll-up as Maddox made a fast count, thus Punk retaining the title. After the match, Maddox attempted to escape from the cell but was attacked by Ryback. After chasing Heyman, Punk attempted to escape by climbing the cell but Ryback followed him and executed Shellshocked atop the cell.
Aftermath
Maddox explained on Raw that he had intentionally cost Ryback the match as a way of making a name for himself and 'becoming famous' after he had been told that he would never achieve his initial dream of becoming a WWE Superstar. Maddox then demanded a WWE contract and a match with Ryback; Mr. McMahon sarcastically replied that Maddox would be given a 'million dollar contract' if he was able to beat Ryback. The match took place the following week, with Maddox being defeated in a squash match and leaving the arena in an ambulance. Ryback then continued his feud with CM Punk, and went on to challenge for the title once again at Survivor Series in a triple threat match with John Cena. It was later revealed on an episode of Raw that Paul Heyman had paid Brad Maddox to make an interference in the match and help CM Punk retain the title.
