Movie two guys on a train coming back home from Vietnam, one is a quarterback and the other is a nerd, and the quarterback recognizes the nerd and they fin out that they are from the same town and same high school. Later on the quarterback is being friendly with the nerd, and the whole movie seams backward.

At the end, the nerd goes to visit the quarterback at his college, and of course, he was invited.

I saw this movie over 10 years ago on TV and don't remember that the I recognized any of them.

Thanks anyway
