Maria Laura (Claudia Fontan) discovers that the right front of his house hides the best kept secret by his brother.
There, in the dark, smelly and abandoned basement, found the strongest evidence: Zodiac Wheel drawn on the wall. Eleven white papers stuck on this great astral circle bearing the name of each sign. Only missing one to complete.
Antonio (Julio Chavez) will not allow Maria Laura meddle in their plans: do not shake the pulse if you have to remove it for its mission - that by which waited 46 years to see it done. Revenge-what the doctor called "corrective cleansing" - will be much more important and relevant than filial love.
