Kezia, Nathaniel and Victor are reunited for the extravagant wedding of a college friend. Now at the tail end of their 20s, they arrive completely absorbed in their own lives but soon slip back into old roles. In the midst of all this semi-merriment, Victor passes out in the mother of the groom's bedroom. He wakes to her jovially slapping him across the face. Instead of a scolding, she offers Victor a story she's never even told her son --- about a valuable necklace that disappeared during the Nazi occupation of France. And so a madcap adventure is set into motion.
