Marisa Ventura is a single mother born and bred in the boroughs of New York City, who works as a maid in a first-class Manhattan hotel. By a twist of fate and mistaken identity, Marisa meets Christopher Marshall, a handsome heir to a political dynasty, who believes that she is a guest at the hotel. Fate steps in and throws the unlikely pair together for one night. When Marisa's true identity is revealed, the two find that they are worlds apart, even though the distance separating them is just a subway ride between Manhattan and the Bronx.

Meryl and Paul Morgan have separated since his infidelity. He's a Manhattan lawyer, seeking forgiveness. She's moved on, focusing on real estate sales. As he walks her to an appointment one evening, pleading his case, they witness a murder; the murderer sees them. The FBI wants them in witness protection until the killer is caught. He's already hunting them. The FBI sends them to Ray, Wyoming, a tiny ranch town, where they stay with the aging sheriff and his gun-toting wife (who's his deputy). Meryl and Paul must sort out their relationship while their New York ways bump up against those of the West. Meantime, Meryl knows two things that Paul doesn't.
