Max Stonecrop, venture capitalist, and Federica Ratzow, pre-med student and polyglot, meet on an overnight train to Venice and then re-connect seven years later when Stonecrop turns up as her patient at Universitätsspital, Zürich. As Stonecrop recovers from a climbing accident and a violent, traumatic experience in Mozambique, they grow close. Federica suddenly vanishes, prompting Stonecrop and Federica’s criminal father to team up against Yakuza gangsters, double-dealing business associates, and dangerous men from Federica’s past.
