The relationship between siblings Alejandro (18) and Rocío (13) faces its greatest challenge when their mother is unjustly imprisoned and they must become parents to their two younger siblings.

As communication between the siblings begins to fail, they learn to believe in each other to find hope on the other side of the wall that threatens to separate them.
