The Perfect Stranger (2011) on Netflix

Plot summary

In a village on a Balearic island, the arrival of an Irishman, Mark O'Reilly, stirs curiosity among the residents. He has moved into an empty storefront that is for sale, and they take his presence as a sign that the old shop will open again. He speaks no Spanish, which leads to misunderstandings and to comic exchanges with the people who seek him out. A shy boy from an overprotective family becomes his friend, and a young woman hiding from the police after a drugs arrest takes shelter in the building. An older woman talks to him without ever catching on that he does not understand her, and the young woman begins teaching him Spanish, starting with slang. An old Polaroid photograph is what brought him to the village in search of answers.
