Small-town astronomer Sam (Matthew Broderick) is devastated when his fiancée, Linda (Kelly Preston), leaves him for French chef Anton Depeaux (Tcheky Karyo) during an out-of-town vacation. Obsessed, Sam follows her to New York City and moves in across the street from Linda and Anton's apartment, where he spies on them and records their lives. One day he is joined by Maggie (Meg Ryan), Anton's equally vengeful ex-girlfriend, and the two plot to break up the new couple.

Washington Square Park

Washington Square Park is one of the best-known of New York City's 1,900 public parks. At 9.75 acres (39,500 m2), it is a landmark in the Manhattan neighbourhood of Greenwich Village, as well as a meeting place and centre for cultural activity. It is operated by the New York City Department of Parks and Recreation. An open space with a tradition of nonconformity, the park's fountain area has long been one of the city's popular spots for residents and tourists. Most of the buildings surrounding the park now belong to New York University. Some of the buildings have been built by NYU, others have been converted from their former uses into academic and residential buildings. The university rents the park for its graduation ceremonies, and uses the Arch as a symbol. Although NYU considers the park to be the core of the school's campus, Washington Square remains a public park, which local residents have protected as an essential part of the neighbourhood.
