Some of the funniest men in movies have combined their prodigious talents in a comedy about, of all things, birdwatching.
Based on a true story, the comic dream team of Steve Martin (Stu Preissler), Jack Black (Brad Harris) and Owen Wilson (Kenny Bostick) are birders who are in a race to tick as many birds as they can in one year in North America.
All are amateur birders, but they long to to be known as the best birder in the country.
Each year birders are challenged to spot the greatest number of species within a single calendar year. The Big Year is the challenge and leads to them criss-crossing the United States many times to increase their bird lists.
Bostick is the reigning champion and record holder and is prepared to put everything, including his marriage, on the line to retain his crown.
