On a summer night in New York City, five lives intertwine and unravel. Isabel, a beautiful twenty-five year old photographer, wavers on her commitment to her upcoming wedding. Her mother Diana, a legendary actress, discovers her husband is cheating. Jonathan, Isabel's fiance, tries to protect a secret that will endanger his marriage. Peter, a young writer, faces his lover's past while researching a story for Vanity Fair and Alec, an actor, wonders if his affections will ever be returned.

Set in the nightspots, theaters, rooftops, and streets of Manhattan over one night, Heights is a contemporary story of young people in New York City that sparkles with the wit that is a trademark of Merchant Ivory films. At the center of the story is Isabel, a young woman trying to decide between her life in the city and the prospect of a quiet existence as a suburban wife.

In a script full of unique New York City settings and characters the story takes us from downtown bars, to upscale roof gardens, to gay bars in Chelsea, to the geriatric participants at a Jewish wedding. Isabel, much like a modern day Jane Austen heroine, a woman on the verge of adulthood must decide in the course of a single night what kind of life she is going to lead.
