It’s a Christian time travel movie where terrorists go back in time to murder Jesus before he can be crucified (therefore preventing Christianity from ever existing) and an atheist skeptic scientist has to go back in time to rescue Jesus, and also rescue his own faith.
I assume that Canada and the USA are more similar to each other than either one is to Mexico. We speak mostly English and we are rich countries. Although some differences will depend on latitude.
As a Canadian I grew up on Americam culture. We are very much sibling countries. They are one big culture together. I know very little about Mexico.
