But when her ex-fiancée moves back to their small Washington town, he is surprised at how bitter and unhappy Sophie has become. He proposes a bet--she must place an ad in the paper that simply states "Wanted: Happiness." If at least 100 people respond, proving happiness isn't a myth, she agrees to a date with him. If not, he'll leave her alone forever. Sophie is convinced she'll win, but fate has other ideas when a reporter at the paper is intrigued by the ad as a story and posts it in newspapers across the country.
