Lockdown featured nine professional wrestling matches that involved different wrestlers from pre-existing scripted feuds, plots, and storylines. Wrestlers will be portrayed as either villains or heroes in the scripted events that build tension and culminated into a wrestling match or series of matches. Traditionally, every match was contested inside a 16 foot high steel structure with six sides known as Six Sides of Steel. The main event at Lockdown featured TNA World Heavyweight Champion Sting defending the title against Mick Foley in a Six Sides of Steel cage match. On the March 19 episode of TNA's primary television program, TNA Impact!, the team of Foley and Jeff Jarrett defeated the team of Kurt Angle and Sting, after Foley hit Sting with a steel chair which allowed Foley to gain the pinfall victory. As a result of Foley's actions, Sting challenged him to a match at Lockdown with the TNA World Heavyweight Championshipon the line. Continuing another tradition of Lockdown events, TNA held the fifth annual Lethal Lockdown match. In this match, one wrestler from each four-member team started in the ring; after five minutes, another wrestler entered, followed two minutes later by a member of the other team. Every two minutes, a new wrestler entered until all ten were in the ring; at this point a ceiling with weapons attached was lowered and pinfalls or submissions were allowed. On the March 26 episode of Impact!, a 20-man Six Sides of Steel Gauntlet match was held to determine the two captains for the match at Lockdown; the last two wrestlers to not be eliminated in the match would win this honor. Kurt Angle and Samoa Joe were last two remaining wrestlers in the contest. Joe refused to be captain of his team at Lockdown so Jarrett was appointed in his place on the April 3 episode of Impact!; setting up the official teams at Lockdown—Team Angle and Team Jarrett. Also on that episode, Booker T, Kevin Nash, and Scott Steiner were chosen by Angle to compete alongside him at Lockdown, while A.J. Styles was given the third spot in Team Jarrett; joining Jarrett and Joe. On the April 10 episode of Impact!, Christopher Daniels was announced as the fourth member of Team Jarrett. The main feud in the tag team division was between Team 3D and Beer Money, Inc.. Beer Money, the TNA World Tag team Champions, granted Team 3D a title shot at Lockdown in Philadelphia. Team 3D, who were the IWGP Tag Team Championsions agreed to the match and announced they would defend their IWGP titles too - making the winner of the match both TNA and IWGP Tag Team Champions.
