Phil and Claire Foster are a run-of-the-mill couple trying to spice up their marriage and their once a week boring date night with a sophisticated evening out on the town. They drive into Manhattan to dine at a fancy restaurant, where they claim the reservation of a no-show couple - the Tripplehorns. Being mistaken for the Tripplehorns, who are actually two people trying to blackmail a prominent gangster, the Fosters are chased across town as they try to get to the real Tripplehorns before the gangsters get to them.
