Jessica is nine years old, lives in a coastal town, and dreams of learning to swim. On the morning her father promises to teach her, men wearing helmets take him away. Since then, Jessica embarks on an unrelenting search: with questions, imagination, and finally, a literal leap into the sea. While the adults remain silent, she confronts a system that stigmatizes and erases. School becomes a hostile space, her mother is lost in grief, and her teddy bear becomes her guide. Inspired by enforced disappearances, Jessica and the Sea is a story about childhood resilience, the power of love, and the right to truth. Through her eyes, the film explores the paths of mourning, where the symbolic intertwines with the real in a quest for justice and memory.
