Erica is a call center operator, which responds to calls made by consumers when they are not satisfied with the product or do not know how to use it. One day she receives a call from her best friend, Sam, who tells him that he saw Alex, her boyfriend in a restaurant, along with a woman who seemed very near.
When you accidentally type the wrong number Sam, and someone answers the phone in a totally different state, Erica realizes that lacks proximity to a person. Thus begins a marathon talks with unknown people whom they call and linking relationships. All you have to do is realize that Alex is the one I want next and if he is faithful.
