The plot is based on the arrival of Aunt Alejandra to a familiar household consisting of two parents and three children.
A woman who is loving, in principle, suffers severe mood swings and strange things happen in her room quite regularly and that seems to be surrounded by an aura of mystery.
Auntie has a fortune that will surely help her relatives, but really begins to destroy the whole family with diabolical acts, and attempts to teach children witchcraft.
Not when graphic violence on screen display, but in a subtle way the sample with an elegant ferocity that causes discomfort even viewer.
With the atmosphere and the magnetic presence of a large Isabela Corona that from a physical get feeble and helpless to convey a menacing tone that seems unfeasible but for the good work between director and actress.
