But when both come up short on the funds needed to afford their dream New York City apartment a mutual friend (Justin Long) re-introduces them and they reluctantly agree to room together. These apartment-mates have nothing in common – until Lauren discovers that Katie is working as a phone-sex operator, and recognizes a good business opportunity. But as their business partnership takes off, their newfound friendship finds unexpected challenges that may leave them both, as they say, hanging on the telephone.
