The Rocket from Calabuch (1956)

Professor Jorge Serra Hamilton, an American atomic-bomb specialist, flees from his transcendental duties to take shelter incognito in Calabuch, a small, idyllic Spanish village on the Mediterranean shores. Oblivious to their guest's eminence, local residents spend their time engaged in their modest daily chores. The affable Professor Hamilton not only integrates perfectly into the small town, forging deep friendships with his neighbors, but he might also be finding the happiness he craves.
