Kate & Leopold are two strangers in New York City, separated by a hundred years. When they meet, a century's worth of differences come crashing together. Kate McKay is a modern-day executive, a 21st century woman driven to succeed in the corporate world. Leopold, the Third Duke of Albany, is a charming 19th century bachelor; each has grown weary of waiting for love. When Kate's genius ex-boyfriend Stuart (who discovers the portal that accidentally transports his great great grandfather Leopold from 1867 to the new millenium) lands Leopold in present-day New York, all must confront the prospect of a love affair 100 years in the making.
