Laguna is a documentary essay dedicated to the memory of the director’s elder daughter, Ina Marija Bartaitė. In the film, Šarūnas Bartas travels with his youngest daughter, Una Marija, to Mexico’s Ventanilla Lagoon on the Pacific coast – the place where Ina Marija spent her last holiday with her father. Immersed in the life of the local community and attuned to the rhythms of surrounding nature, father and daughter reflect on loss and the fragility of life.
