Libby Hart and Matt Ogden are perfect for each other - as friends. They've known each other for ages. They act as each other's plus-ones. They even share custody of a dog. And if there's always been a little spark between them, so what? It's never been worth jeopardizing their friendship.
Professional rugby player Matt is fighting for a starter position with the London Legends - and that's not the only thing he's fighting. A crippling fear of flying means he's struggling to get his career off the ground. He has no time for a relationship, even if Libby does make him ache. As an airline pilot, Libby's looking for a stay-at-home husband so she can have a family without sacrificing her high-flying career. Matt's certainly not that man.
But just because they don't have a future together doesn't mean they can't have a right now. When Matt asks Libby for help overcoming his fear, they agree to take a vacation from their platonic relationship - whenever they fly together, they can have sex. It's the perfect way to resolve all that built-up tension. As long as they can avoid getting a little too comfortable....
