Three years after life got in the way of their long-distance relationship, Californian illustrator Zoe and English engineer Martin have an unexpected opportunity to reunite- a second chance to follow in the footsteps of pilgrims in Europe. This time, they won't be walking the famous Camino de Santiago to north-west Spain but the less travelled Chemin d'Assise and Via Francigena to Rome, the mountainous path down from rural France. And rather than each setting off solo, they will accompany Zoe's old friend Camille-who, despite her terminal illness, insists she will walk the whole sixteen hundred kilometres to seek an audience with the Pope-and her not-so-ex-husband, Gilbert, who sees the trip as a gourmet tour. Then Bernhard, Martin's young nemesis from the previous trek, shows up, along with Martin's daughter, Sarah, who is having a quarter-life crisis and doesn't exactly hit it off with Zoe.
