At everyone the hobby, and supervision over birds isn't worse at all, than philately and other hobbies. Styu Prissler , Brad Harris and Kenny Bostic, so to speak, observers with an experience: their experience in supervision over birds is widely known to people around. Once all three, without arranging, decided to arrange to themselves "The Big Year". Big year is an informal competition for fans of birds who arm with field-glasses and straighten ears to hear and see as much as possible different types of birds in a native habitat.
The one who in 365 days will make the longest list, becomes a winner. All three athletes for the sake of the big year absolutely forget about private life and work. Styu , the head of the large company gathering for pension distracts from a large deal, Kenny's marriage will just about be scattered because of his love to ornithology, and Brad tries to find in supervision over birds a way out of the hatred to work. For all three competition becomes business of the first importance.
