Arachnid Infestation is a chilling suspense thriller that plunges viewers into a deadly and relentless struggle for survival. Told through shifting perspectives, human and otherwise, the story unfolds as a city is rocked by a sudden surge of brutal, unexplained deaths, turning ordinary spaces into lethal traps.

Morgue technician Betty, who harbors a lifelong fear of spiders, becomes entangled in the mystery after examining victims whose injuries defy natural explanation. As panic grows and authorities struggle to contain the chaos, the spiders continue to adapt and multiply with unnerving precision, pushing the city toward collapse. Each discovery raises deeper questions about the nature of the outbreak and whether the threat was ever accidental at all.

Writer Biography - Rehanna Loncar

From an early age, I was captivated by the art of storytelling, the kind that keeps you on the edge of your seat, heart pounding, breath held. Whether it was the eerie silence before chaos erupted or the creeping tension that seeps into your bones, I knew I wanted to craft narratives that made audiences feel something visceral.
My passion for suspense and horror runs deep. I thrive on weaving tension into the ordinary, turning the familiar into something unsettling, something unforgettable. My writing is fueled by a love for atmospheric dread, grounded realism, historic events and the thrill of pushing characters beyond their limits.
With Arachnid Infestation, I set out to create a chilling, pulse-pounding experience, one that doesn’t just scare but lingers long after the credits roll. I believe the best horror isn’t just about what lurks in the dark, but how people respond when the darkness comes for them.
