The pleasures of food, of the erotic, of family - form the very fabric of our emotional lives. And smell is an essential emotional trigger. There is more truth to call our sense of smell our sense of desire because it springs our passions. Smell moves us, subliminally and profoundly. It moves us to act and do things we are wholly unaware of. It enriches our lives, gives us with unspeakable joys. All along this feature-length documentary, central storylines take us into the world of smell. Many of them have the suspense, death-defying risk and insanity of a an ultimate quest. Others, are moments of pure poetry.
