So Stratham is an undercover DEA agent & tries to retire undercover ...
So, Stratham is an undercover DEA agent in a biker gang. Then, he tries to retire undercover, in the backwoods of Louisiana.
Yet, in both incarnations, he retains the strongest possible English accent.
I mean, it's not even a "Canadian"-ish accent that he could (possibly) use as his backstory. No. It's a completely, unreconstructed English accent.
How is this remotely plausible?
