On Hold (2011)

Between the city and the countryside, the subtle and modern forms of slavery unfold. A girl waits for the pick-up truck that will transport her to the city. Once there, amidst a never-ending row of walls and fences, she peeks into the entrance to a school. Lined up and in uniform, those girls are not the ones Carmen will join.

Unfortunately the movie On Hold is not yet available on HBO Max.
