Le Birdwatcher (2000)

In 1975, American ornithologist Charles Williamsen travels to the French Basque country to observe birds. Staying in a luxury hotel, Williamsen makes friends with the other international guests, including Spaniard Miranda Fernandez and British bird-hunter Mitch Glassborough. But while Williamsen insists he's just a simple bird-watcher, his unusual equipment and curious activities suggest otherwise.
