In the summer of '65, four friends make a mad dash to Vegas to get married before midnight to avoid facing the Vietnam draft.

So they are 2 couples, and it's a speed race. I like it, but for those who are not familiar with the story It could be useful to specify that they are 2 couples in my opinion. I Still think that if it's a comedy, they could be 4 boys that travel to vegas as many couples did to avoid the draft but they have to find the girls too. Very difficult and more heroic!

>>>But, many husbands were drafted.

IF they married after August 26, 1965 (in which case they no longer qualified for the marriage deferment).

But, many husbands were drafted. You should put it that they get married in Vegas and flee to Canada to avoid the Vietnam draft.
