You see, Mac the Mallard is a troubled father who finds solace in the fact that his family is stranded near an autumn pond somewhere in the Adirondacks. Here, dangers do not lie in wait for the herd at every turn: no huge buildings, no men with guns, no predators. However, this state of affairs does not sit well with Mac's wife and their growing children. They are eager to go to winter in the southern regions.
"I don't want to lose my life because you won't leave this pond," Pam tells her distraught husband. And this ultimately decides the fate of the family. Led by Mack, the Biscuits first go to New York, fly from New England, and then continue to the Caribbean Islands to warm their feathers under the bright winter sun.
