Character mistake: Deni tells Anne she got a report from a scout 1,800 klicks west from here. She might have meant 18, but 1,800 doesn't seem logical. A klick is 1 kilometer (or 0.6 miles). It's unlikely a scout is over 1,110 miles away, which would put him in the middle of Texas.

Starring: Will Patton, Noah Wyle, Drew Roy, Maxim Knight
Factual error: When Tom has decided his scout group will have to go for the food and then his look for his son later, they are stood on a green. There is a war memorial dedicated to both World Wars, 1914 - 1918 and 1939 - 1945. That's got to be in Canada, as the USA didn't enter either war until later than those dates. (00:28:00)
