A young woman with a camcorder shows up at her estranged grandparents’ house on the Galician coast, looking for answers her family doesn’t want to give.

That’s the setup for “Romería,” Carla Simón’s latest feature, opening June 26 at Film Forum in New York. The film follows 18-year-old Marina, a budding filmmaker who needs a signature from her paternal grandparents to attend university in Barcelona. But what starts as a bureaucratic errand becomes something deeper. Armed with her deceased mother’s diaries and her camera, Marina tries to piece together the truth about her parents and her father’s death. Her relatives welcome her, sort of, but dodge her questions at every turn.

Simón knows something about mining family history for story. Her debut “Summer 1993” was autobiographical and won three Goya Awards. Her follow-up “Alcarràs” took home the Golden Bear at Berlin and represented Spain at the Oscars. “Romería” premiered at Cannes last year and played the New York Film Festival.

Shot along rocky Galician coastlines with what critics are calling “sun-dappled” cinematography, the film tackles a universal question: what were your parents like before you knew them? For indie filmmakers building stories from personal history, that’s fertile ground.
