Susana is shown being restrained and then thrown into a cell in a reformatory wherein this young woman soon realizes that for company she has rats and scorpions. It seems clear that Susana had escaped and has been apprehended. She is being punished. Susana, terrified, prays to God and cries his help and soon flies out of a iron window in the wall, after a cross shaped light throws a reflection on the floor. Outside, it is a virtual deluge and soon she takes refuge at a hacienda, wherein a kindly looking family give her bed and food and kindness. Susana is however not welcome to the elderly maid who sees in the rain and in Susana's appearance a bad omen, a devilish act.
Susana is blonde and beautiful and it is soon clear that she is about to create havoc in this household as all the three men, the master, his young son and ranch hand all fall for her. Susana's goes in a well planned manner to seduce all three, creating friction in the household. However, the ranch hand gets to know that she is an escapee from the nearby reformatory and blackmails her into loving her. Susana uses one against the other and eventually her identity gets revealed and she is dragged, virtually back to the reformatory. We never really get to know why she had in the first place been incarcerated there and what her crimes are though it does seem that she might somehow be mentally unbalanced.
