An American photography scholar working in Holland has befriended the ten-year-old son of colleagues there. Over the next two years, Will is increasingly caught up in tensions between Sander's mother Marijke and her estranged husband Niek over his growing intimacy with Sander. And the boy himself - lovable but difficult - is ever more demanding. As Sander's twelfth birthday draws near, Will has to decide whether to return to San Francisco and the security of an academic life, or remain in Amsterdam, where he must face the risks of his friendship and Sander's expressed need for him.
