"Lagnat" is a Tagalog horror animation about Jun, a young boy who falls ill with a high fever in a remote, rural village. As his condition worsens, strange and eerie occurrences begin to unfold around his home—shadows move in the corners, whispers fill the air, and his feverish dreams seem unnervingly real. His family initially dismisses it as a common illness, but when Lola Rosa, the village healer, warns that Jun's sickness might be caused by a malevolent spirit trying to claim him, they realize it's more than just a fever.

Desperate to save Jun, the family turns to old folk remedies and protective rituals to fight off the unseen entity. As the fever peaks, the spirit grows stronger, and the line between reality and the supernatural blurs. The family must confront the dark force before it takes Jun forever.

"Lagnat" explores the intersection of illness and the supernatural, drawing on Filipino beliefs about sickness being tied to spiritual forces, creating a tense and eerie atmosphere throughout the story.
