Barbara, the loving elder sister, meets Nick and falls in love with him. Nick is smitten with Barbara in return, while Ruth also declares her love for Nick. This love triangle sets the stage for the conflicts to come.

Ruth confesses she loves Nick and threatens to kill herself if he does not marry her. Barbara reluctantly agrees and convinces Nick to court Ruth to avoid losing him to her sister. The arrangement is made behind Barbara's ambivalent sense of duty.

Nick agrees to marry Ruth, not out of affection for her but to honor Barbara and fulfill Ruth's demand. The wedding is arranged as a twisted pledge to Barbara's happiness. The family is pulled into a perilous deception.

Ruth marries Nick in a forced union. After the wedding, she ends her life by suicide, leaving Barbara and Nick reeling from the tragedy, with Ruth's daughter Karen as a witness. The family mourning is immediate and heavy.

Barbara flies back to the Philippines to mourn Ruth and comfort her niece Karen, who bears the trauma of the event. Bewildering occurrences begin to unfold around the house, hinting at Ruth's unsettled spirit. The atmosphere grows increasingly tense and ominous.

Beatriz and Barbara hold a séance to reach Ruth, hoping to lay her spirit to rest. Ruth's spirit briefly possesses Karen and mortally wounds Beatriz, who then drives the spirit away. The attempt reveals Ruth's lingering influence and sets the stage for further hauntings.

On what is believed to be Ruth's ninth day of haunting, she grows more powerful with aid from evil spirits. The truth is later revealed to be the eleventh day, prompting a desperate plan to rescue the family from Ruth's escalating menace. The haunting intensifies as the danger nears the home and resort.

Sofia, Beatriz's apprentice, visits Nick in the hospital to warn him that Ruth's influence could escalate and urges him to join forces to stop her. Barbara and Karen's safety become central as Ruth's power increases. The protagonists brace for a dangerous confrontation.

Ruth's spirit once again possesses Karen, attempting to harm their yaya Benita while Barbara intervenes to protect her family. The haunting intensifies as Ruth's control tightens over the household. The danger affects every member of the family directly.

Barbara uses a holy prayer to break Ruth's possession over Karen and frees her from her mother's spirit. The family regroups, sensing the danger is far from over. The moment marks a temporary reprieve amid the escalating supernatural threat.

Ruth reappears and urges Barbara to join her in hell, while Karen pleads for her aunt's safety. Ruth unveils a fiery fissure to separate Karen from her aunt and threatens to claim them both. The confrontation reaches a climactic, almost surreal level.

Sofia tells Nick he is the key to stopping Ruth, and he confronts the supernatural threat. He sacrifices himself by holding the embodiment of Ruth, plunging with her into hell as Barbara and the others watch in horror and mourning. His act is framed as a final, noble attempt to save his family.
