John Clark (Richard Gere) is a man with a wonderful job, a charming wife and a loving family, who nevertheless feels that something is missing as he makes his way every day through the city. Each evening on his commute home through Chicago, John sees a beautiful woman staring with a lost expression through the window of a dance studio. Haunted by her gaze, John impulsively jumps off the train one night, and signs up for ballroom dancing lessons, hoping to meet her. At first, it seems like a mistake. His teacher turns out to be not Paulina (Jennifer Lopez), but the older Miss Mitzi (Anita Gillette), and John proves just as clumsy as his equally clueless classmates on the dance floor.
