In Your House was a series of monthly professional wrestling pay-per-view (PPV) events first produced by the World Wrestling Federation (WWF, now WWE) in May 1995. They aired when the promotion was not holding one of its then-five major PPVs (WrestleMania, King of the Ring, SummerSlam, Survivor Series, and Royal Rumble), and were sold at a lower cost. Breakdown: In Your House was the 24th In Your House event, and took place on September 27, 1998, at the Copps Coliseum in Hamilton, Ontario, Canada. The name of the event was about D-Generation X, whose entrance theme was called "Break It Down".

The event comprised twelve professional wrestling matches with outcomes predetermined by WWF scriptwriters. The matches involved wrestlers portraying their characters in planned storylines that took place before, during, and after the event.

The main feud heading into the event was between "Stone Cold" Steve Austin, and Vince McMahon, who did not want Austin as the WWF Champion. On the September 5 episode of Raw Saturday Night McMahon criticized, and insulted The Undertaker, and Kane for failing to dethrone Austin. On the September 6 episode of Sunday Night Heat, McMahon apologized, and scheduled Austin to defend his title at Breakdown against both in a Triple Threat match. On the September 14 episode of Raw, McMahon added a stipulation that The Undertaker, and Kane could not pin each other. He then confronted Austin, who attacked him. The Undertaker and Kane broke up the attack and later that night interfered in Austin's match with Ken Shamrock. With the help of The Rock and Mankind, Austin fought off the attackers and chased after McMahon, who was watching from the aisle. On the September 21 episode of Raw, The Undertaker and Kane defeated Austin and Billy Gunn. After the match, Austin hit The Undertaker and Kane with a chair. McMahon made one more stipulation if anyone interfered in the match on Austin's behalf then Austin would automatically be stripped of the Title.

On the same night, to prevent Shamrock, The Rock, and Mankind from teaming with Austin, McMahon allowed them to win a shot at the WWF Championship in a Triple Threat match. The match ended in a no-contest when The Undertaker and Kane attacked the three contestants. The Triple Threat match was rescheduled for Breakdown. to be contested inside a steel cage.

Lower down the card, Dustin Runnels clashed with Val Venis. Dustin's new gimmick was that of an evangelist who preached against the vulgarity of the WWF's Attitude Era, mainly its violence, bloodlust, and sexual content, making Venis, whose gimmick was that of a porn star, a prime target. Venis responded the following evening on Raw with a film involving Runnels's wife, Terri, who had been absent for almost a year. On the September 13 episode of Sunday Night Heat, Dustin jumped through the crowd and attacked with a religious-themed sign, using the wood to choke him. The following week, Dustin, who was providing commentary, assaulted Venis, who was busy fighting Owen Hart, but Venis managed to tie him up in the ropes and deliver a promo further insinuating the details of his adulterous relationship with Terri.

Despite featuring prominently on the promotional poster, Triple H did not participate in the event, due to a legitimate knee injury.
