The Idea of North

In the guise of chronicling the final moments of three polar explorers marooned on an ice floe a century ago, Baron's film investigates the limitations of images and other forms of record as a means of knowing the past and the paradoxical interplay of film time, historical time, real time and the fixed moment of the photograph. Marrying matter-of-fact voiceover and allusive sound fragments, evidence and illustration, in Baron’s words, "meaning is set adrift".
