A puppet-starring fish story. When their car breaks down in the middle of nowhere, a mother and son wind up in Lunker Lake, a small fishing community that "you've got to be lost to find." The town is abuzz over the upcoming fishing contest, since the winner gets to decide the water level of the lake for the coming year. Naturally, there's a mean, rich bad guy in town who wants to win by any unscrupulous means possible so he can flood the town for his own advantage. But the town's best fishermen -- with the help of the newcomers -- may yet prevail.
