Mia and Jake have known each other their whole lives. They've endured summer vacations, Sunday brunches, even dentist visits together. Their mothers, who are best friends, are convinced that Mia and Jake would be the perfect couple, even though they can't stand to be in the same room together.

After Mia's mom turns away yet another cute boy, Mia and Jake decide they've had enough. Together, they hatch a plan to get their moms off their backs. Permanently. All they have to do is pretend to date and then stage the worst breakup of all time - and then they'll be free.

It's the perfect plan - except that it turns out maybe Mia and Jake don't hate each other as much as they once thought . . .
