Mild-mannered accountant Sandy Patterson (Jason Bateman) has his identity stolen by a slippery thief (Melissa McCarthy).

His credit rating ruined and job at risk, he sets off to collar the culprit, which involves the mismatched duo in a disaster-strewn journey from Florida to Denver.

This road movie comedy produces plenty of laughs thanks to the irrepressible force of comic mayhem that is McCarthy, while Bateman is an excellent foil.

The film runs into sentimentality at the end, but the stars’ comic friction works splendidly and there are some satisfying jabs at social inequalities along the way.
