Fast-forward fifteen years: single thirty-something Ted needs to resolve his feelings for Mary, and is convinced by friend Dom (Chris Elliot) to hire inept detective Pat Healy (Matt Dillon) to find her. Healy returns from Florida smitten with Mary, and misleads Ted about her circumstances (overweight, wheelchair-bound mother of 5), then moves to Florida to pursue Mary for himself. Ted discovers Healys ruse when high school friend Bob (Willie Garson) reports having seen Mary at a convention just weeks earlier. Dom convinces Ted to locate Mary, then joins Ted after bailing him out after hes mistakenly jailed on his way to Florida. In the mean time, Healy has been wooing Mary, but another of her admirers, architect Tucker (Lee Evans), has undermined Healys efforts by feeding Mary incriminating information about him. Once in Florida, Ted bumps into Mary accidentally, and they begin dating. Healy confronts Tucker, and the two team up to undermine Ted budding relationship with Mary.
