Overview:

Benno and Allegra: he's over fifty, English, and drinks like a fish; she's twenty years younger, a travel blogger with lots of imagination. They both live off their lies and have no intention of stopping now. Next-door neighbors who had never met until the day he wound up on the wrong landing, and nothing would ever be the same. Sheer chance leads this odd couple on a flight towards lost or forgotten places, where their mutual support makes for self-discovery.
