Florida resident Diana (Melissa McCarthy) has a luxurious lifestyle as the queen of retail, buying whatever strikes her fancy -- and it's all free, thanks to Sandy Bigelow Patterson (Jason Bateman), a guy from Denver whose identity she stole. With just one week to track down Diana before his world implodes, the real Sandy heads south to confront the unapologetic con artist and bring her back to Denver so that he can clear his name and restore his shattered credit rating.
