バスの下に潜むエイリアンの恐怖

A packed city bus tears through rainy streets at night. Suddenly the entire floor dents upward beneath passengers’ feet with a metallic BOOM. People scream as scraping sounds race underneath the bus at impossible speed. Sparks blast past the windows. A passenger looks down outside — an alien creature is sprinting upside down beneath the chassis, weaving between axles. The driver slams the brakes. The floor rips open from below as the creature bursts upward into the aisle.

through the shattered windshield, the bus skids while the creature crawls across the ceiling inside the overturned bus toward camera.
