Two narratives intersect in the surfing documentary The Lost Wave: An African Surf Story. At its center lies the on-camera journey of famed surf explorer and pioneer Sam George, who joins two traveling companions (Joe Curren and Holly Beck) on a dazzling exploratory expedition to the tiny island of São Tomé (one half of the country São Tomé and Principé, in the Gulf of Guinea, just off of the African coast) to investigate the unusual permeation, into that indigenous culture, of surfing with flat, finless boards. Upon arrival, George hopes to bank off of the local enthusiasm for the sport and use it to rekindle his own passion for cresting waves. On a deeper level still, however, the tale lingers of the island's troubled history - a history that involves colonialism and longstanding slavery. E! reporter and surf fanatic Sal Masakela narrates.
