Hannah's Vegas vacation is supposed to be four days of cocktails, blackjack, and freedom before she goes back to managing chaos for a living.
Instead, she wakes up hungover, naked, in a luxury hotel suite she doesn't recognize with only fragmented memories of the night before and a very attractive, tattooed stranger still asleep in the bed.
Escaping before he wakes up seems like the smartest option. Unfortunately, things get much worse when Hannah discovers a diamond ring on her finger and realizes she may have done the most cliché Vegas thing imaginable.
With an emergency pulling her back to Los Angeles, no memory of what happened, and a mystery husband she hasn't even identified yet, Hannah is about to find out that what happens in Vegas definitely doesn't stay in Vegas.
