Cántico is a documentary on the life and poetry of Pablo García Baena, the leading exponent of the poetry movement formed around the journal of the same name. It begins as a diary of the making of the film, showing us the difficulties of the project. The poet, at the age of 94, though the project had come too late, with most of his colleagues already deceased. But once he opens the doors of his house; his photographs, possessions and books provide a sensory journey through the aesthetic of his poetry and his experience of language.
