What happens in Vegas, stays in Vegas...Right?

Molly Day's life is usually pretty uncomplicated, but after a series of hapless romances, she finds herself being packed off by her employees for some well-deserved vacation time in Vegas. She had planned to soak up the sun, take in some shows, and enjoy being free and single again, but only Molly could end up married to a stranger! Anna Garcia has a career and a life plan all set out, which doesn't include meeting Molly. What starts off as dinner results in a night of tequila, great sex, and wedding rings. This is a marriage of inconvenience for both of them, but getting it annulled isn't quite as simple as Anna thinks. Panicked, she returns to LA, leaving Molly with no way of contacting her, and her only option is to return home and try to forget all about the best mistake of her life. So, when Anna turns up at Molly's coffee shop four months later, Molly is convinced she's there for a divorce. How wrong could she be? Anna wants to give it a go! Can two people fall in love when they're already married, or will it just be something that happened in Vegas?
