It was the fifth annual Vengeance event. Professional wrestling is a type of sports entertainment in which theatrical events are combined with a competitive sport. The buildup to the matches and the scenarios that took place before, during, and after the event were planned by WWE's script writers.

The main event was a Hell in a Cell match for the World Heavyweight Championship between Batista and Triple H, which Batista won by pinfall after executing a Batista Bomb. One of the predominant matches on the card was John Cena versus Chris Jericho versus Christian in a Triple Threat match for the WWE Championship. Cena won the match and retained the title after pinning Christian. Another primary match on the undercard was Kurt Angle versus Shawn Michaels in a rematch of their bout at WrestleMania 21.
