Shall We Dance? (2004)

For longer than he can remember, John Clark has led a dull existence--and even with a successful career, charming wife and loving family, he still feels something is missing as he makes his mind-numbing commute through the city each day. But one night, on his evening ride home, he looks up to see a beautiful woman staring through the window of a dance studio. Haunted by her gaze, John impulsively jumps off the train and signs up for dance lessons--and his whole life begins to change. Now, he's entering a world he never imagined--the colorful world of competitive ballroom dancing. It's a place filled with grand passions, bitter rivalries, great friends and strange couples and it's about to reignite the excitement in John's life--not to mention the lives of his family, dance instructors and fellow classmates--in ways he's never dreamed.
