"Lihim ni Rose (Part 1 of 2)" is a Tagalog horror animation based on a true story about a young woman named Rose who moves to a new village to start fresh. As she settles in, she becomes aware of the local legends surrounding aswangs—supernatural creatures that prey on humans, particularly women. Initially skeptical of the stories, Rose dismisses them as mere folklore.

However, she soon begins to experience strange occurrences—unexplained noises at night, shadows lurking around her home, and a growing sense of unease. Her neighbors warn her about the aswang, urging her to be cautious, especially when night falls. Despite their warnings, Rose feels drawn to a mysterious figure she sees in the woods, which only heightens her curiosity.

As the narrative unfolds, Rose discovers that the aswang may have a personal connection to her family’s past, raising questions about her own identity and the secrets hidden within her lineage. The story ends with Rose facing a choice: to confront the dark legacy tied to her family or continue living in ignorance.

In this first part, the animation sets the stage for a suspenseful exploration of fear, heritage, and the unknown, emphasizing the chilling atmosphere of the village and the deep-rooted beliefs about aswangs.
