The plot itself is simple. Woodrow T. Grant (Bruce Dern) gets a letter that says he’s won $1,000,000 and decides to go and claim his prize. There are only a couple of problems. Firstly, he lives in Montana, and needs to get to Nebraska. The trip is about 800 miles, but he has had his drivers’ license revoked.
The second problem is that the letter is a scam.
