Reminds me of a movie called ( El Parramo ) The Squad.

This movie is almost identical to another one I saw called The Squad.
In this Colombian made film some soldiers came to an abandoned outpost and
find everyone else missing.
However they find this old woman walled up alive in one of the buildings.
Afterwards these soldiers start losing control of themseslves and come to
believe that this woman they found behind the wall is a bruja or witch.
They start fighting and killing each other just like in this movie.
I wonder which movie was inspired by the other.

It is difficult to free fools from the chains they revere.
