Based on the true saga of the Stouffer brothers, this movie is an unusual combination of comedy film and nature documentary. In the 1960s in rural Arkansas, Marty Stouffer (Jamey Sheridan) grooms his three sons to take over the family auto parts business. But the sons are more interested in animals, photography, racing cars and trucks, and impressing girls. Marty, Jr. (Scott Bairstow) and Mark (Devon Sawa) fight frequently with their stern father over his work demands and their yen for adventure. Finally, their mother Agnes (Frances Fisher) intercedes, and the patriarch agrees to let the two boys take a cross-country trip to film a nature documentary. The youngest son, Marshall (Jonathan Taylor Thomas), stows away in his brothers' van and joins them on their travels. They head west, encountering a variety of animals and surviving many dangerous scrapes. The brothers' wacky exploits contribute to a new kind of participatory nature cinematography. In real life, the Stouffer film was shown on national television in 1977, and all three brothers became documentarians and served as advisers on this film biography.
