There are three things you should know about Cate Ortega. One, she's a jet-setting flight attendant who never takes vacations. Two, she's competitive enough to lose friends over a game of Monopoly. And three, she's recently been dumped by her pilot ex-boyfriend for the blonde, new hire.

So, when a man calls out her name in the coffee shop and she absent-mindedly responds, Cate quickly realizes her private and routine life is about to be turned upside down. Theo asks her to pretend to be his girlfriend before his brother walks in and against all logic and reason, she agrees.

But when meeting Theo's brother turns into her attending his brother's wedding weekend in Hawaii, Cate and Theo make a deal. She'll pretend to be his girlfriend for the wedding and meet his entire family, if he goes to her company's New Year's Eve party as her date, showing her ex-boyfriend that she's moved on.

Once the year ends, so will their relationship. But when they're forced to spend more time together than originally agreed upon, Cate starts to wonder if she'll be able to walk away, or if what started off as fake could be turning into something real.
