I didn't know that cuz I didn't watch it yet and I only saw the trailer

Your correct but one thing if you see the outside you do suicide that's why they have blindfolds

Otherwise something bad happens(again I only saw the trailer)

It's about a mom who gave birth to 2 children at a dangerous time and at the dangerous time had a creature (idk wat it was looking for I only saw the trailer) the world was in jeopardy from it and if you wanted to escape it you needed a blindfold otherwis

But after I get back from the store I'm going to ok
