Not being a history expert, I don't how much of this short dramatization is accurate. Knowing Hollywood, I have my doubts.
The second half is the dramatic part as one man rides bravely, fending off bullets and other obstacles, to cast his deciding vote at the last minute to give the U.S. it's "Declaraton of Independence." That man is Delaware's "Caesar Rodney." I guess I learned some history because I had never heard nor read of Mr. Rodney before this film.
Meanwhile, we see Thomas Jefferson, Ben Franklin, John Hancock, John Adams and others as they write and vote on the famous document, giving the "rebels" their victory over the "Tories," as explained in this work.
For someone who watched TV shows in the 1950s, seeing John Litel, who played a villain in a lot of those shows (like Steve McQueen's "Wanted: Dead Or Alive series), playing Jefferson was a little strange and a stretch for me.
Overall, as entertainment, it was okay, watchable but not something I'd look at again.
