Antonia Quirke and Caitlin Benedict visit the Midnight Sun Film Festival in Lapland, where the sun shines for 24 hours in summer and films are shown every hour of the day. There they speak to Iranian exiles Mohsen Makhmalbaf and Marzieh Meshkini, Brazilian director Fernando Meirelles, French auteur Arnaud Desplechin and Mark Jenkin from Cornwall.

Along the way, they meet the people who make the festival possible, the volunteers, and find out why all the directors are expected to get into a sauna and go skinny dipping.
