Did You Hear About the Morgans? (2009)

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, and the murderer sees them. The F.B.I. wants them in Witness Protection until the killer is caught. He's already hunting them. The F.B.I. 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 City ways bump up against those of the West. Meantime, Meryl knows two things that Paul doesn't.
