Hi. the truth is not explained very well in the context of the short, what is the relationship that these three individuals have. The mother is the woman in a thin black dress, the man is the one who has a lock and smile constantly. possibly more than a home, it is a base of operations where many tools and torture rooms are being built. The only family that I saw among the group, was the drawing of the goat that the girl made (typical of parents hanging the drawings of childhood).
