Flying-phobic ER nurse Olive Murphy is still gripping the armrest from her first-ever take-off when the pilot announces an in-flight medical emergency. Olive leaps into action and saves a life, but ends up getting stuck in the airport hours away from the marathon she's running in honor of her brother. Luckily for her, Stella Soriano, the stunning type A copilot, offers to give her a ride. After the two spend a magical day together, Stella makes a surprising request: Will Olive be her fake girlfriend? A video of Olive saving a life has gone viral and started generating big sales for Stella's airline. Stella sees their union as the perfect opportunity to get to the boys' club executives at her company who keep overlooking her for a long-deserved promotion. Realising this arrangement could help her too, Olive dives into memorising Stella's comically comprehensive three-ring-binder guide to fake dating. As the two grow closer, what's supposed to be a ruse feels more and more real. Could this be the romantic ride of their lives, or an epic crash and burn?
