Feeling stuck at work and tired of London's dreary weather, magazine writer Dylan Coughlan impulsively rings a radio station one day only to win a once-in-a-lifetime trip around the world. The catch? Her travel partner must be a contact randomly selected on her phone. The number lands on "Jack the Posho", an uptight, unbearably posh guy she met on a night out and accidentally ghosted. The two couldn't be more different, and as the trip kicks off, Jack seems like he'd sooner fling himself into the sun than have a conversation with Dylan. After a poorly-received article about her past abortion went viral, a chance at a permanent column hinges on the trip, and Dylan's willing to do anything to make the series a hit, even if it means embellishing her and Jack's relationship to satisfy readers.
