Ground Zero: In Your House

Ground Zero: In Your House was the 17th In Your House professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on September 7, 1997, at Louisville Gardens in Louisville, Kentucky. This was the first three-hour In Your House pay-per-view, and also the first to use the "In Your House" moniker as the subtitle rather than the main title. This was also the last event in which the entrance staging shaped like a suburban home was used, in favor of unique sets based around the name of the PPV going forward. The event is notable for featuring the first-ever singles match between Shawn Michaels and The Undertaker.

Eight professional wrestling matches were contested at the event including one dark match which took place after the show. The main event of the pay-per-view (PPV) portion saw Shawn Michaels and The Undertaker wrestle to a no contest, while in the final match for the live audience The Undertaker and Hunter Hearst Helmsley wrestle to a double count out. Also on the card, Bret Hart defeated The Patriot to retain the WWF Championship, The Headbangers (Mosh and Thrasher) won the vacant WWF Tag Team Championship in a Four-Way Tag Team Elimination match, and Brian Pillman defeated Goldust. Due to prior stipulations, Goldust's manager/wife (storyline and real-life) Marlena was required to become Pillman's assistant for 30 days.
